Integra travels towards a castle via helicopter. Outside the castle, her forces are about to enter. Fargason contacts her and says he does wish they had more intelligence on this castle. Integra says it can't be helped, but he is to assess the situation inside quickly and subdue the freaks. Walter then tells her that the castle is the property of a Japanese firm, but it's currently up for auction. Integra thinks the castle is the ideal home for a mock vampire.

As Seras runs towards the castle with the rest of her unit, she thinks that running with the Harkonnen is such a bother. The unit prepare to move in. Meanwhile, Integra's helicopter lands in a field next to the castle. As Integra steps out of the helicopter, she is unaware that she is being watched by someone.

The Hellsing soldiers find a corpse on some stairs, which have had a cross painted onto them. As the soldiers start searching the place, Seras can sense something and sees something strange at the top of the stairs. She mumbles that something is wrong. Captain Chris Pickman asks about what she just said. Seras says there is something here. But Chris is then told to pull everybody out of the castle.

Outside, the SAS arrive. Second Lieutenant Parker walks over to Integra and tells her that he is ordering her organization to make a complete withdrawal. Integra says this tainted castle must first be purified by the Hellsing organization. Parker says the situation has changed, they've discovered that the IRA have been using this castle as a weapons depot. There is a high possibility that some of the most wanted terrorists in the country are still hiding inside. Even if they have become something inhuman, that doesn't mean their guilt as terrorists has suddenly been erased. They already know about Hellsing's gear and strategies. He tells Integra to try and remember her outfit isn't the only one trying to protect this country.

As he walks off, Fargason asks Integra if they're packing up. Integra says she'll file a complaint with the JIC, but tells Fargason to withdraw. Seras is still in the castle, as the SAS troops swarm in. She then hears Alucard's voice, who tells her that her intuition is getting sharp. He says that the battle they are joining now is unlike anything she has seen before -she needs to prepare herself. Seras thinks it almost sounds like her master is enjoying this. Alucard says he is.

When Integra gets back to the Hellsing HQ, Walter says that Laura has been waiting for her. Integra initially seems confused, but then sees Laura and realizes it's her dear sister. They go to Integra's office, where Integra tells her she should have called ahead -although it's still good to know she still hasn't mastered basic etiquette. Laura says that all of the family living in Avon are doing well. She asks Integra if she ever gets lonely living here.

Integra tells her she can stay here for the night and will have Walter prepare a room for her. Seras goes back to her room and is about go go to sleep, but realizes she can't do so without taking a bath first. She gets up, but then senses something wrong above her and wonders what it is.

She goes up to the main hall and sees Laura walking up some stairs. Walter then appears out of nowhere. Seras asks who that girl is. Walter tells her it's Laura, who is Integra's younger sister. Seras thinks that's strange, since the two don't even look alike... although she guesses the Hellsing family has a complex history.

Walter then clutches at his heart. He asks to be excused, claiming he sometimes forgets he's not as young as he used to be. As he walks off, Seras looks back up at the stairs, only to see that Laura has gone. She thinks that something's not right.

At the castle, Parker asks how you can get lost in a castle this small. It reminds him of a ghost story he read once, where Nazis invaded Transylvania and were stationed at a castle that had a demon in it. He asks the guy with him if he's listening, only to find out that he's become a ghoul. Inside the castle, Paul Wilson is asked by Incognito for his name. Paul says it, as Incognito asks him if he wants to live, if he wants to live forever.

Paul says he doesn't know. Incognito asks him if he wants to stay in the form of a man, broken and imperfect, or does he want to become a perfected being? As he says this, several creatures carrying freak chips appear. Paul says he wants to be perfected, that's why he has been training himself and joined the SAS, although it hasn't been working out. Incognito asks him again if he wants to live forever. Paul says he does, so the creatures start implanting numerous chips into his body.

Integra has fallen asleep at her desk, and has a strange dream. Meanwhile, Alucard has gone to find Incognito. He asks him what he's doing here and wonders if his hunger has driven him to this. He gets no response, so he says whilst he doesn't know his name yet, he thinks he has a lot in common. He knows his enemy has also put aside his pride and learned to bow before human masters, which he thinks is pitiful.

Integra wakes up to find herself in Laura's arms. Laura starts to undress her. Seras again senses something wrong and goes to investigate, only to find Walter waiting at the bottom of the stairs. He warns her to not dare to try disturbing Integra. He then throws out one of his wires, which cuts Seras' face.

Integra realizes that she doesn't have a sister, she's never had one! Laura bites her breast as Integra calls her an evil bitch -how dare she does this to her! Meanwhile, Alucard hopes Incognito does have some power to back up his enormous pretension. He then hears someone walking towards him.

Incognito appears, and knows who Alucard is. Alucard asks what he should call him, so Incognito says his name. Alucard thinks he's a nobody, but he can live with that, as his own name is a bit of an enigma as well. He pulls out the Jackal and says they're both originals who are bound by humans, so they can take their time and have some fun.

Laura licks Integra's breast. Integra asks her if her use of the name Laura is some sort of a sick joke. She knows there was a Laura who was taken by the Countess of Karnstein. She wants to know what the baobhan sith's real name is, and asks if it's Camilla. She then asks if her Hellsing ancestors destroyed Laura's people? As Integra asks her if she came her for her petty revenge, Laura grabs a knife and stabs it into Integra's stomach. Outside, Seras asks Walter to wake up. Laura tells her big sister she has such a dirty mouth.

Alucard asks Incognito what he's waiting for, doesn't he carry any human weapons? Incognito reveals his grenade launcher, which Alucard finds quaint. He wonders what type of ammunition it has, so Incognito empties a grenade. Alucard thinks it's sorcery from the dark continent, but says that's perfect -they can begin.

Incognito then speaks, saying that the two of them are different. The difference between them is that Alucard doesn't have a master any more. As Integra weakly cries out Alucard's name, Incognito shoots Alucard, damaging one of his shoulders.

Seras had pulled her gun out, but Walter uses his wires to tie her up. Alucard laughs and says he'll fill Incognito's flesh with his Jackal's bullets. Back in Integra's office, Laura says Integra's blood is delicious. Integra asks if she thinks she's torturing her. Laura says no, she's only doing what she was told to. She'd been told not to make her into a ghoul to quickly, but now it's just about time to take care of that.

She tells Integra she'll chew through her neck and drink up every last drop of her delicious blood. Then she'll give her just a little bit of her own blood, just a taste of it since she can't make her one of them. She'll turn her into nothing but a mindless ghoul. Integra sees the knife and reaches out for it, but Laura then bites into her neck.

A pentagram then appears above the Hellsing HQ. Walter suddenly comes to his senses and releases Seras, whilst he wonders what he was doing. Alucard sees Laura and says he's had enough of her mockery.

Laura jumps over the desk and leaps towards Alucard, but he fires the Jackal and kills her with one shot. Her body crumbles to dust, just as Seras and Walter arrive in the room. They see that Integra has picked up the knife, and has it placed next to her own neck. She tells them to stay back.

She plunges the knife into her neck and collapses, saying that there is impure blood in her veins...
