Pressed for time, Michael tries to enlist the help of his cell mate, who asks for a transfer when he realises what Michael is planning to do.

As the riot escalates, Michael risks everything to rescue Sara; the assassin tries to kill Lincoln; Veronica and Nick fly to Washington to trace the tipster's phone call.

Michael sacrifices Fibonnaci to Philly in order to restore Abruzzi as commander of the prison's work detail and put the escape plan back on track.

Abruzzi's demotion puts the entire escape plan at risk; if Michael protects the new inmate, T-Bag threatens to expose the plan to the guards.
