rescues her from them. However, the rioters follow her and Michael, who try to evade them. Sara asks how Michael knows about the pipes and he replies by saying that he has had PI duties to clean up toxic mold in the pipes. Soon, Michael is able to knock out one of the leading inmates and rush to an exit. However, when they arrive, a sniper, sent by Govorner Tancredi, who is adamant to do what it takes to rescue his daughter, aims at him. Michael quickly ducks as the pursuing inmates are fired at and Sara reunites with her father. Veronica and Nick arrive in Washington D. C. and receive the address from the placed phone call, a payphone. The payphone is next to the building of the company the Vice President uses. The phone rings and Veronica answers it. The caller tells them that they are dead. In a panic, Veronica and Nick run away from the payphone. Michael returns to gen-pop and reunites with Lincoln before heavily armed SORT teams invade the prison and force the inmates back to their cells. In Michael's cell, the team discuss what to do with Hudson. Michael, Lincoln and Sucre want to keep him alive.
