A series of flashbacks to three years ago unveils how Lincoln, Sucre, T-Bag, C-Note and Dr. Sara landed in Fox River State Penitentiary, and what drove Michael to craft his elaborate plan to break his condemned sibling out of the prison.

Michael, Lincoln and Kellerman face several roadblocks as they attempt to capture a protected Terrance Steadman; tragedy strikes the Mahone family; Bellick turns sour when a fellow inmate turns sweet on him; C-Note faces life on the run as a single parent; and T-Bag forces the Hollander family to play house with him.

Michael and Sara become more than "strangers on a train" en route to confront the President; Mahone recruits an new ally in his attempts to capture the fugitives; T-Bag puts on a happy face when the welcome wagon arrives; and a fourth escapee takes a fall.

Michael and Sara realize that Warden Pope (guest star Stacy Keach) is the key to recovering information that will bring down "The Company"; Mahone corners another escapee; C-Note fears for his daughter's life; Sucre learns the dangers of hitchhiking en route to reuniting with Maricruz; and T-Bag walks down memory lane when he takes the Hollander family to his childhood home.

While Russell deals with the shooting death of her father, Sipowicz and Medavoy try to dig up evidence on an eight-year-old murder case.
