Moreno tries to handle things, but Frears and Sasha are part of the crew, as is Perkins, who was an inside man that is leading this operation. Frears and Sasha are hackers who messed with the building's shredder so that up to $600 million would pile up, which is what the crew plans to steal. Unfortunately for them, the codes to the safe containing the money has been changed, and only Casey knows the new code.

He tries to go after them with Jaqi and another goon, but Jaqi ends up driving into a gas station where she dies in an explosion. Dixon and Xander also show up to make trouble. Will manages to hook the tower to his car, and Casey starts to pull so it can come down, just as the crooks nearly have the codes they need to unlock the safe.

Perkins disagrees and shoots Dixon dead before prompting the other corrupt cops to join him so that they can live and keep some money.Will and Casey hide out in the only mall in town. He is upset with her because she won't give up the codes so easily because he thinks she is just trying to get her old job back, but she is trying to use it as leverage because otherwise the villains will kill off hostages if she lets them get the money. Casey contacts Perkins to let him know where they are after they let her and Will speak to Moreno and Breeze. Perkins sends some goons to the mall to find them.
