Michael has his hands full when Sucre turns traitor and escapes with the newly found $5 million; Mahone is investigated by Internal Affairs regarding Tweener's death; Lincoln is determined to reunite with LJ, but may be walking into The Company's trap; and Sara must fight for her life when the conspiracy tries to make history repeat itself.

Michael and Sara's reunion is anything but romantic as Mahone and Kellerman are determined to keep them apart - permanently; Lincoln receives some help from a father figure as LJ meets a long-lost relative; Sucre plans a getaway with Maricruz; and T-Bag runs into a familiar face while holding the key to his freedom.
