S5·E3 Prison Riot

A riot breaks out at the prison, where two inmates are killed. The squad goes to the scene, but Frank must still stay behind. Bayliss, Lewis, Kellerman and Howard interview the inmates; many of them have familiar faces. Frank works on his target practice. Bayliss thinks that one inmate really wanted to tell him something, so he puts together a deal to get the information. The inmate confesses to the murder and Bayliss doesn't believe him. Another riot breaks out and the truth is finally discovered.
