The season opener finds Michael Scofield in Sona, a hellish and deadly Panamanian prison where a previous riot has forced all authority out and has left the prisoners in charge of their own lives (and deaths). With the fate of his loved ones hanging in the balance, Michael must to find Whistler, a mysterious fellow inmate hiding within the prison's sewer system, in order to break him out from a prison from which there is no way out. Meanwhile, Lincoln searches for a missing Sara and receives troubling news about LJ.

Michael races to find a hidden Whistler before Mahone; searching for clues outside the prison, Lincoln runs into an old friend and makes a new one: T-Bag slithers his way into Lechero's graces as the prisoners threaten a revolt due to the lack of agua (water).

Determined to speak with Sara, Michael enlists T-Bag's help to get to the only phone in Sona: Lechero's; Lincoln attempts a daring rescue; Whistler comes clean to Michael, just as Mahone is tempted to fall back on a dirty habit; and Bellick makes an enemy while attempting to get back on his feet.

A prominent family meets their new neighbors in the only Departure-free town in America.

After his failed attempt to rescue LJ and Sara, Lincoln receives a deadly warning from The Company; Michael formulates an electrifying escape plan from Sona; Mahone is haunted by a face from the past; and T-Bag crawls up the ladder as Bellick lands in hot water with Lechero.
