~ Hawkes is called to Pennsylvania State Penitentiary. A man named Reggie Green requested that Hawkes be there for his execution. Hawkes doesn't know the man, but he gets there just in time to exchange a few words with Reggie. Before Reggie gets led off to be executed, he delivers a shocking blow: he's the one who killed Hawkes' sister Grace. Hawkes is stunned, but he doesn't get to ask any more questions as they lead Reggie away--they're on a schedule.
~ Hawkes watches them hook Reggie up to deliver the lethal injection--but one of the guards isn't acting right. He collapses onto the floor, blood coming from his mouth. The other guard yells for a doctor. Hawkes rushes in, kneeling to check on the man, but it's too late--he's dead.
~ The warden orders the guards to take Reggie back to his cell, and Hawkes takes the opportunity to call Mac. Meanwhile, a group of sheriff deputies arrive and head for the crime scene--but one of them breaks away and takes a different path. He pulls a gun on the guard in the control room, demanding that he release one of the prisoners. When he doesn't move, the deputy pulls the trigger.
~ Hawkes hears the sound of a gunshot and hangs up the phone, heading toward the control room with the warden. When they see that the guard is dead, Hawkes rushes off to chase the shooter--ignoring the warden's calls for him to stop. It's only after Hawkes has pushed through a door that he realizes what's wrong. There's a full-on riot taking place in the prison. Hawkes turns to run back the way he came, but the door closes--he's trapped with the inmates.
~ A bit later, back at the lab, Mac is trying to get ahold of Hawkes--they're watching the news coverage of the riot, and they realize that Hawkes is basically a hostage. If the inmates find out he's a cop, he's dead.
~ Adam points out something: Shane Casey was transferred to Pennsylvania State Penitentiary.
~ In the middle of the riot, it's obvious that the inmates know Hawkes doesn't belong. They start to attack him, but someone rushes in to help--it's Reggie. He gets Hawkes out of harm's way, and they duck into a side room. Before Reggie can say anything else, Hawkes attacks him--this is the man that killed his sister. Reggie doesn't fight back, but Hawkes can't do it. He's not a killer. He lets Reggie go.
~ Reggie rushes out of the room just as Hawkes' phone rings. Mac and the rest of the team are huddled around a speaker phone, and they ask if he's alright. Mac tells him to conserve his cell phone battery.
~ When they hang up, Mac tells the team to get blueprints of the penitentiary. Stella knows what Mac is getting at: they're going to break Hawkes out of prison.
~ Meanwhile, Reggie returns--with a prison uniform. If Hawkes is going to survive, he's going to have to blend in with the inmates. Reggie wants to help Hawkes, but Hawkes doesn't care--helping him won't make up for his sister's death. But Reggie needs to tell Hawkes the truth. He needs to explain. He accidentally killed Grace when he was high, and he told the police she was killed by her drug dealer--but Grace had already beaten her own drug addiction. Her only mistake was trying to help him. All these years, Hawkes assumed his sister died because of the drugs. Reggie wants to help Hawkes out of the prison for Grace's sake, not for his own.
~ Hawkes wants to find Shane Casey's cell--he thinks Shane is behind the death of the first guard and the subsequent prison riot. He can't let Shane escape in the midst of the chaos.
~ For those who are keeping track, Mac, Stella, Danny, Lindsay, Hawkes, Flack and Adam are all mentioned, so Sid seems to be rotated out in this episode.
