After raising the suspicions of the Panamanian Army, Michael sweats out solitary Sona-style while Bellick weathers the fight of his life. Susan sets her sights on Sucre as T-Bag schemes his way into the escape.

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.
