Morrigan watches a program called Can You Believe It?, where the host says viewers will get to see the first clear videotape of Sasquatch. The video shows the Sasquatch immediately turn around and moon to the camera, which Morrigan thinks is rude. Morrigan asks Demitri why the wretched humans can find the other Darkstalkers, but he fails time and again.

Demitri says finding Darkstalkers is no problem, and has Ship display the locations of all those with Darkstalker blood. Ship does so, and Demitri says finding them isn't the problem, recruiting them for their cause is the problem. Morrigan sees there aren't many of them left. Demitri asks why there's so few, and wonders if he's sure he's showing all of them. Ship says the reason for the scarcity is unknown -insufficient data. He also asks not to be called "Ship". Morrigan wonders if someone has been eliminating their kind, but Demitri thinks that's not possible -they're too strong for humans to destroy.

On Earth, a werewolf called Hendrick Farr is found by Hsien-Ko. Hendrick asks who or what she is, and she tells him he's been found guilty of crimes against human kind. She asks if he has any justification for his actions, and he says he's faster, stronger and smarter than humans. He takes what is his right, so who is she to judge him? She says she's not his judge, as the Lady of Mercy has seen to that. She's here to carry out the sentence.

The next day, Felicia arrives at Harry's home. Harry leads her in and says she's got to see this -he was checking out a news group on the net, and he says something really weird happened last night in Cape Town, South Africa. Felicia reads out what's on the screen: the body of Hendrick Farr, CEO of Land & Ocean Investments, was found on Clifton beach. Witnesses said it looked as if he was attached by a wild animal of unusual size. Felicia asks what that has to do with them, and Harry says he's checked and there aren't any large predators down on the Cape. He thinks it's a Darkstalker, but Felicia thinks it could just be an escaped zoo animal. Harry thinks it could be a werewolf, and wants to check it out, but Felicia declines, as she knows Harry needs to go to school occasionally, even if he is in the advanced classes. But she relents and decides to ask Rikuo to take a look.

On Pyron's ship, Morrigan tells Demitri that someone down there is destroying them, and she's going to find out what it is. Demitri thinks it's probably just a mistake on the ship's part, and as he keeps telling her, they can't be destroyed. Ship says if that's true, how come there's so few of them? And he doesn't make mistakes. Morrigan says they've got to find out what's happening. Demitri says Lord Raptor is in South Africa, so he'll have him investigate. He's certain Raptor will find nothing.

Meanwhile, Raptor is on the phone, complaining to Irv about how much this tour stinks on ice -they've only sold 12 tickets last night! Demitri then contacts him, and says he has a job for him. Raptor thinks it has to be better than this, and asks what it is. Demitri instructs him to go to Cape Town, and check out any reports of sorcerers or anyone capable of harming them. Raptor heads off, and arrives at Clifton beach. He bets he's chasing a wild goose.

But he then finds Hsien-Ko. He asks who she is, and she introduces herself as a hunter of evil. Raptor laughs and tells her she's found it, and then shoots at her.

Hsien-Ko gets up and says she didn't expect another battle so soon, as her prey rarely comes to her. She charges, only for Raptor to blast her. As he gets closer, she kicks him down.

She changes her arms into weapons, and asks who sent him to find her. Raptor doesn't tell, so she slices his guitar apart. She wants a name, but he tells her there's nowhere to run to.

She says they'll try again: she needs the name of the one who sent him here. She fires a boomerang projectile, which Raptor ducks, but it comes back and explodes under him. Hsien-Ko asks for the name again.

He tells her to get over it, and knocks her over. She kicks him again, and then transforms one of her hands into a cannon. She says that the Lady desires his presence.

She fires a shot at him, which blows him away. Rikuo then emerges from the sea, and tells them to stop right there. Hsien-Ko thinks Raptor has called for reinforcements, but they'll won't help him. She says she's hunted the evil ones for more than a century, so she's more than a match for both of them.

Rikuo says there's been a misunderstanding, as he's not evil. He refused to join the Darkstalkers when they ordered him to. Hsien-Ko says she doesn't believe him -although he's strangely attractive for a fishman. She goes to attack him, but he jumps over her.

He then gets attacked by Raptor, so he has to jump back. He hits Raptor with a smelly projectile, which forces him to run off and jump into the sea.

Hsien-Ko says she is a ghost, and has no need to breathe, so Rikuo's magic won't work on her. She attacks him, but he dives out of the way. Raptor then runs up to her, but she smacks him away.

Raptor is then beamed up to Pyron's ship, and shouts Demitri's name and he goes. Hsien-Ko recognizes that name, but then tells Rikuo that evil must be punished. She launches her hands at him, one of which grabs his throat. He asks if she's a coward, and she says she's been called many things, but never that.

He says she's attacking him with her spinning tin toys, whilst he's unarmed. She brings back her weapons, and asks if that's better. Rikuo says much, and then hits her with a water blast.

She tries charging into him, but he inflates himself, leading to her bouncing off. She teleports behind him, but he leaps out of the way and says he's not evil. She says she's been told that before, but evil often lies. She then says all Darkstalkers must be destroyed.

However, Rikuo traps her in a bubble. He says he won't hurt her, but this was the only way he could stop her long enough so she'll listen to him. He explains that there are those of them with Darkstalker blood who reject Demitri, who are not evil. She asks why he's here, and he says he was investigating the possibility that there may be a new Darkstalker. She believes he too was hunting Hendrick Farr, but he says no, and then realizes she was the one who hunted him. He asks why. She says he was a werewolf, a Darkstalker, who had been preying on people for decades. The Lady wants humans protected from his kind, so he had to be stopped. Rikuo asks who this "Lady" is.

Hsien-Ko asks to be let out first, so Rikuo hopes she won't attack. Rikuo pops the bubble, and she apologizes for attacking him. She says she hasn't heard Demitri's name in so long, and starts to explain that it began when she and Mei-Ling were 12...

Their father welcomed the visiting Demitri Maximoff to their land, and invited him into their home, as father's superior had asked him to do. Soon after Demitri's first visit, their mother disappeared. 6 years later, Demitri came back, seeking unique sculptures -or so he claimed. Again, their father welcomed him into their home. That night, something woke her up, and she went to check on their father, only to find Demitri there.

Demitri claimed that a messenger had come, and their father left immediately. He then looked at her, and she couldn't move. Her sister, Mei-Ling, then came out and bumped into her, which freed her from Demitri's trance. Demitri tried to grab them, but they managed to evade him.

They ran outside, and Demitri chased after them. He managed to grab Mei-Ling, but she told Hsien-Ko to run and get away.

Years went by, and Hsien-Ko was too afraid to return to town, fearing Demitri would find her. She wandered the roads, begging for food. One day, she went inside the ruins of an ancient temple, and found what she thought was a jar of rice. She ate the contents, not knowing it was actually an ancient powder of ground topaz, and as the old stories told, such things transform people. It made her what she is today: a ghost. The Lady of Mercy, Quan Yin, came to her then.

Back in the present, Hsien-Ko says Quan Yin told her she was no longer human, she was immortal. She pleaded with her to become mortal again so she could find her sister, but the Lady said it was impossible. Rikuo thinks that doesn't sound very merciful, but Hsien-Ko says her mercy isn't always the same as theirs. She offered her the chance to become her hunter, as there were those like Demitri, who preyed on the weak, who were not her children. Since then, she has been doing her will, making this world safer for humankind. Some day, she will find Lord Demitri Maximoff.

Up on Pyron's ship, Raptor is complaining about what happened. Demitri realizes he made a mistake sending Raptor there, whilst Raptor is upset that his Stratocaster has been broken. Morrigan says she told him not to send Raptor, so he tells her if she's so certain of everything, she should deal with it.

Morrigan asks if he's putting her in charge, but he says he's giving her an order -if she thinks she's up to it. Morrigan says she's more than a match for any human, no matter what magic they use. She's beamed down, and fires a blast at Hsien-Ko and Rikuo.

They see Morrigan, who fires at them again. Hsien-Ko says this must be one of the evil ones, and Rikuo says it's probably Morrigan, who's a sorceress as well as a Darkstalker. Hsien-Ko says it's enough to know she's evil, and flies over to where Morrigan is waiting.

Morrigan summons a sword, and starts fighting Hsien-Ko. Hsien-Ko says she knows she serves another. Morrigan decides to warn her that she doesn't fight fair, but Hsien-Ko knows her kind never does. She manages to knock Morrigan's sword out of her hands, and says fair or foul, she's no match for her!

Morrigan tries to get the sword, only for Hsien-Ko to knock it out of her hands again. Morrigan tries another spell, but seems to be out of energy. Hsien-Ko pins her down and asks if she has any reason for her to not end her miserable existence right now.

Morrigan asks what sort of reasons would she like. Hsien-Ko asks her if she knows of the one who calls himself Lord Demitri. Morrigan says she knows of him far too well. Hsien-Ko says she has an affair of honor to settle with Demitri, so Morrigan says she could bring him to her. Hsien-Ko says that if she can bring Demitri to within her arm's reach, she has her word that she'll let her live. A short time later, Demitri beams down from the ship.

Demitri says he thought she could handle the hunter by herself. Morrigan says the hunter isn't what they thought -she's like them. She's heard of him, and wants to join. Demitri sees Hsien-Ko, but when she looks at him, she thinks back to the time her sister was caught by him.

Demitri puts her into a trance, and says she's a mere human. He remembers who she is, and says her sister was... delectable. Rikuo then appears, and tells Hsien-Ko to not let Demitri touch her. Demitri tells Morrigan to deal with him.

However, Hsien-Ko breaks free from Demitri's trance, and tries to attack. Demitri jumps up to avoid her strike, and says she's making this easy. He fires a projectile at her...

...but she's able to bounce it back. She changes her hands into maces, and attacks Demitri with them. Meanwhile, Morrigan blasts away at Rikuo.

He finds a small fountain, and uses it to blast Morrigan with water. Meanwhile, Demitri teleports behind Hsien-Ko.

He grabs her by the throat and says she's now his, just as her mother, father and sister were. She kicks him off, and tells him to not ever mention them -he has no right. He's deprived her of her parents, her sister, her childhood and her life. Over 100 years of guilt for escaping him, when they could not.

She vows he won't harm anyone else, ever again. She starts spinning rapidly, and he tries to get out of the way, only to have most of his hair cut off. Morrigan laughs and tells him that's a good look for him, but Rikuo then jumps onto her.

She manages to kick him off. Demitri says nobody touches him, and fires a projectile beam at her, which she blocks. They continue to fight, but Demitri teleports again.

He strikes her from behind, and says he's the master of the Darkstalkers. He starts to prepare another attack...

...but then screams, and sees the sun is rising. He asks Morrigan for help, but she declines. He summons a coffin, and gets inside it.

Morrigan opens it, and Demitri screams, so she closes it again. Rikuo then grabs her, and tells Hsien-Ko that this is her chance to destroy her too. But Hsien-Ko says Morrigan gave her Demitri, so she goes free.

Rikuo says he never promised Morrigan anything, and tells her to say goodnight. Morrigan tells Ship now, and she is beamed up. Rikuo has to let go of her, but as he lands, Demitri's coffin is then beamed up.

Hsien-Ko tries to stop it, but when she touches the beam, she's bounced off it. She can only watch as the coffin is beamed up, and breaks down in tears, believing that she's failed. Rikuo tells her there will be a next time, and tells her to think of all the lives she's saved by hunting and destroying evil. She may not have saved her own family, but she's saved many others.

Quan Yin then appears, and says that Rikuo is right. Hsien-Ko thinks it's all useless, but Quan Yin tells her she has learnt tears again, compassion for herself, not just the rest of the world -that's a victory in itself. Hsien-Ko hugs her, and says she is indeed the Lady of Mercy.

Rikuo gives his thanks too, as Hsien-Ko does not stand alone in fighting evil. Quan Yin says that whilst he is not human, he is indeed one of her children. She then floats up, and disappears. Hsien-Ko tells Rikuo that if he needs her, call. No matter when she is, she will hear.

She then leaps away. Later on, Felicia and Harry talk about what happened. Harry says he's found out that what he'd read about was actually a ghost who hunts Darkstalkers, but now knows that some of the Darkstalkers are good. So now, she only hunts the evil ones. Felicia thinks that's great, as they really don't need a second Donovan to watch out for. Harry wishes he got to meet her, as she's Chinese, and might have been able to teach him Chinese magic. Felicia is sure there will be other chances to meet her.
