Prison Break Season 4 (Serial 6)

After escaping from the hellish Sona Prison in Panama, brothers Michael Scofield and Lincoln Burrows decide to take justice into their own hands and bring down The Company, the shadowy organization that has ruined their lives and murdered Michael's beloved Dr. Sara Tancredi. When Michael discovers that Sara is still alive, the brothers realize that the only way for them to return to a normal life and gain complete freedom is to find Sara and destroy The Company once and for all. With the help of a government agent, they form a new team including Mahone, Sucre, Bellick, and some new members, all working together to accomplish this seemingly impossible mission. Unfortunately for the brothers, they also have to figure out a way to recruit T-bag, as he holds valuable clues (likely Whistler's book) that are essential for their plan. In the end, they will discover that infiltrating the enemy from within is even more challenging than escaping from prison.
