Heavy rains force Michael to move up the escape timetable and break out of Sona that evening. Another inmate joins in on the escape, and T-Bag and Lechero form an alliance as Bellick hopes to form one with Mahone. Lincoln and Sucre help bring the lights down on Sona.

Michael & Lincoln must handover Whistler to Susan so they can save LJ and Sofia's lives; Mahone seizes a golden opportunity; T-Bag shows Sona who's boss; a familiar face enters Sona as another leaves it in a body bag.
