Sub-Zero and Sonya enter a theatre, looking for Kano and his Black Dragon thugs. Sonya turns the lights on, but they see how run-down the theatre is. Sub-Zero says there's no sign of the Black Dragon. Sonya contacts Liu's group, but finds out they've found nothing either. Sonya is convinced the Black Dragon could be hiding underground, as her old partner was this close to finding them before Kano and his goons blew him away. When she finds Kano, she has a major score to settle.

Liu says that Nightwolf's radar detected some kind of powerful energy pulses coming from beneath this area, so it's probably something to do with the Black Dragon. Liu tells her not to take any chances. Sonya turns more lights on, but as soon as she does, she and Sub-Zero come under attack from fireballs. Sonya fires a projectile back.

The fireballs keep coming from somewhere in the stands, as Sonya says this is a tough audience. She leaps forward and gets to where the rows of chairs are, but then gets shot at again. Sub-Zero asks her if she's alright, but doesn't get a response. He contacts the rest of the team and says this is a kombat alert -they need backup! Liu says they're on their way.

Sonya then gets hit, causing her to be launched through a few rows of chairs. She's about to be hit by another blast, but then someone else suddenly appears and gets her out of the way. He picks her up and runs out of the theatre with her. Sub-Zero sees this, but then gets hit by a fireball. He then hears some rumbling beneath him.

It's the rest of the team, who've arrived in the dragon jets. Sub-Zero tells them that Sonya has been taken. Stryker asks if it was the Black Dragon, but Sub-Zero says it was too dark to tell. Elsewhere, Sonya wakes up and wonders where she is. She then sees the guy who came to her aid standing in front of her.

He tells her not to be afraid, as he isn't her enemy -although the real enemy is very near. She asks who he is, but he tells her to stay where she is. She tells him he saved her life back there, so now she wants to know who he is. He tells her to stop, but she goes up to him anyway. When she sees his face, she gasps. He tells her she now sees why he prefers to remain hidden. He says they've met before, and tells her his name is Kabal.

Kabal puts his mask back on, as Sonya says she's sorry, she just wasn't expecting that. She then hears a noise and asks of there is a portal down here, but as she goes to check it out, Kabal stops her. They both get down, as a couple of fireballs zoom over them and strike the ceiling, causing it to collapse.

They hear some voices in the distance. Sonya says it's kombat time, but Kabal stops her from rushing off to fight. He tells her she's too weak, and leads her way. He kicks down a ventilation shaft cover and helps Sonya climb into it. They then head down the tunnel, away from their pursuers.

Kano's gang arrive, but realize the ones they're after have escaped. Kano appears and tells them nice work, they've let Kabal get away again. The emperor isn't paying to let Kabal make fools of them, so the next time Kabal shows up, he'll have a special surprise for him.

Sonya tells Kabal she doesn't get it. He's quit the Black Dragon, so what's he doing now? Kabal says he learnt his lesson when this happened. Before he can continue, he hears some voices in the distance and says it's more Black Dragon. But Sonya says it sounds like her guys, and goes up to them. But when she turns around, Kabal is gone.

Liu says Nightwolf just barely tracked the signal from Sonya's trashed wrist com. The team decide to go back to base, where Sonya explains what happened with Kabal. Jax says he's not sure about this, if Kabal is sneaking around under the city, how do they know he's not working for the Black Dragon again? He might have just been putting on a show to win their confidence. Sub-Zero says this is suspicious.

Sonya believes the reason Kabal is hiding is because he feels like a freak. Stryker says maybe that's because he is a freak. Sonya tells him to back off, as Kabal didn't ask to look that way. Jax thinks she has to admit Kabal is a little bit bizarre. Liu asks how Kabal ended up like that anyway. Rayden says Kabal's "friends" turned on him...

Many years ago, Kabal was a loyal and valuable member of the Black Dragon, being one of their most ruthless assassins. But the emperor Shao Kahn learned that Kabal was destined to reform, to become one of the chosen. So he ordered his warriors to annihilate Kabal. They attacked him without mercy, but he narrowly escaped with his life. But he was left forever scarred and forced to rely on a respirator.

Jax notices Sonya crying and says if he didn't know better, she actually cares about this guy. Sonya tells him in his dreams, she's just allergic to his cheap cologne. Nightwolf then says he's detecting heavier power surges now, from the same abandoned subway tunnels they were in before. He says it's as if someone were running some huge machine and drawing a tremendous amount of electrical power to do it. Liu says it's got to be the Black Dragon, they must be using the electrical grid from those unfinished subway tunnels as some sort of power source. Sub-Zero asks why they'd need that much electrical power. Liu says he doesn't know, but maybe they'd better go back there and take a closer look.

The team arrive at the place Nightwolf says the power source is. Sub-Zero asks him if he's certain this is the spot, as there is no evidence of the Black Dragon here. But Jax then finds a bat with the Black Dragon symbol on it. Sonya says this was the last thing her partner saw before Kano...

Before she can finish, Nightwolf contacts Liu and says he's been monitoring their positions. It looks like the power source they're searching for is right under their feet. There is then an explosion on the tunnel, knocking one of the dragon jets aside. The group flee down a tunnel and see that a portal has opened up inside the subway. It shoots up a burst of energy which goes through the ceiling and into the sky.

Someone then steps out of the portal. Sub-Zero says it's Hideyoshi, the deadliest of all of Shao Kahn's assassins. Hideyoshi then charges. Stryker jumps back, but Hideyoshi still manages to grab him and throw him into a wall.

He then attacks Kitana, striking the ground with his spear and making the ground crumble beneath her. She falls, but manages to grab onto the ledge. As Liu and Sonya go to help Kitana, Hideyoshi is about to go after them. But Jax gets in his way and starts fighting with him.

Liu helps Kitana up. Sub-Zero throws an ice projectile which hits Hideyoshi's arms, freezing them up. But he's strong enough to shatter the ice. Before he can do anything else, Kabal suddenly appears, using his great speed to run around Hideyoshi and make him spin.

Kabal then kicks Hideyoshi in the head a couple of times, making him stumble back and go through the portal. The portal then closes up. Sonya says she owes Kabal another one, but he says they all need time to recharge after their battle. He says he has a place that the Black Dragon can't find.

Sonya says it's a nice place Kabal's got here. Kabal says it suits his needs. Sonya asks why it's so hidden away. Kabal says that from this place, he can watch the movements of the Black Dragon and do what he has to to stop them. Sonya says in other words, he's decided to wage his own private little war -why? Kabal says the day Shao Kahn's assassins did this to his face was the day he knew his life had stood for nothing. His redemption must be born of his own crimes, and that he was fated to haunt this subterranean word like a phantom, striking at the Black Dragon and vowing to destroy the very evil which had spawned him. Sonya asks if he ever gets lonely here, why doesn't he fight the Black Dragon above ground?

Kabal says his appearance gives him little choice, the world above is repelled by what it does not understand. Even she was frightened at first, but not anymore it seems. He asks her why this is, even when her friends find him hard to look at. Sonya says that Maggie, her best friend when she was seven, had an accident where she ended up in a wheelchair. Suddenly everyone started treating her like she was different. It drove Sonya crazy, why couldn't anyone see past that chair? Kabal says unfortunately there are too few people around like Sonya. Nightwolf then tells Liu he's detecting more power surges in their area. Liu says that energy turned out to be a portal, so the Black Dragon must have built some machine to rip the dimensional fabric -the subway power supply must be running it. Nightwolf says these new pulses are ten times the magnitude of the others, so the Black Dragon must be about to open a new, bigger portal.

Liu says rest time is over. They've got to infiltrate the Black Dragon base and make sure they don't open a new portal. Sonya asks Kabal if he knows how to get them there. Kabal says he does, but there are too many of the Black Dragon, even for them. Their base is well-guarded, so the only hope is if one person can slip in undetected. He volunteers himself, and heads off.

He gets to the Black Dragon base and defeats a couple of guards. The door requires a retina scan, so he uses one of the defeated guards and scans their eye, which opens the door. He gets inside the base and plants a bomb, but then Kano and some Black Dragon appear. Kano tells him he's afraid he can't let him do that.

He deactivates the bomb. He says that with this gadget, he can open portals to all realms. He'll then amass armies for Shao Kahn, and for his own purposes. He calls Kabal a fool for turning against the Black Dragon. Whilst he's truly sorry for what Shao Kahn did to him, he says that betraying the Black Dragon was an even bigger mistake. Now, he'll have to pay. A portal is activated, as Hideyoshi reappears. Kano tells Kabal that Hideyoshi and the boys are going to take care of him and then his little pals.

Kabal runs around the Black Dragon, knocking them all down in seconds. But Hideyoshi proves to be a much more capable fighter, who this time attacks with a whip. Kabal gets thrown across the room, but then Sonya yells it's kombat time. She and the rest of the team have arrived in the base.

The team start knocking the Black Dragon through the portal. Jax uses his ground pound to put Hideyoshi off balance, and then starts punching him repeatedly. Hideyoshi ends up falling back through the portal.

Kano tells Sonya that they meet again. He asks if she's missed him and then tries to kick her, but she grabs his leg and then hits him with an elbow smash, sending him flying. She tells him she hasn't missed him as much as he's going to miss his teeth, but before she can get to him, another Black Dragon tackles her.

As Kano runs off, Kabal rushes over and hits the Black Dragon, knocking him into the portal. Stryker then seals up the portal. Liu tells Kabal that they're sorry for interfering, but Sonya wouldn't stop nagging them until they tracked him here. Kabal says Sonya has a strong will, but now it's time to finish what they began.

He reactivates the bomb. The team head back to the dragon jets and take off. As they leave, Kano contacts them and tells them so long -they win again, for the moment. He says this is a little going away present for them, and has explosives detonate throughout the tunnels. But the team manage to get out of the subway.

Back at the base, Liu thanks Kabal and tells him to consider joining up with them full-time. Kabal says he would be honored, but the time is not right. Sonya asks why not, as his home has been blown into space dust, so he could at least stay here for a while. As the rest of the team leave, Kabal takes his mask off and tells Sonya he's so touched by her kindness. She's given him hope others might see past his appearance. But he knows he must find a new home and renew his battle against the Black Dragon and Shao Kahn's legions of darkness. He tells Sonya that he must do this alone.
