The third season finds Michael Scofield (Wentworth Miller) back in prison with disgraced FBI Agent Alexander Mahone (William Fichtner), ex-prison guard Brad Bellick (Wade Williams) and villainous Theodore "T-Bag" Bagwell (Robert Knepper). But Panamanian prison Sona is no Fox River -- the inmates run the ruthless penitentiary on the inside while armed guards beyond the fence stand ready to shoot any would-be escapees. At the top of the prison pecking order is murderous drug lord Lechero (Robert Wisdom), who tells the new inmates that disputes are resolved via the gift of a chicken foot, which signals an inmate's desire to fight another to the death. Lechero immediately distrusts Michael for fear that his celebrity status as an escape artist may threaten his rule. Outside Sona, Michael's brother Lincoln Burrows (Dominic Purcell) tries to get his sibling transferred to another prison, but his efforts are derailed when Michael's love interest Sara Tancredi (Sarah Wayne Callies) and Lincoln's son LJ (Marshall Allman) are kidnapped by a merciless operative who calls herself Susan B. Anthony (Jodi Lyn O'Keefe). In order to save Sara and LJ, she tells Lincoln that Michael must locate fellow prisoner James Whistler (Chris Vance), who has information coveted by The Company, and break him out of Sona. Lincoln serves as the middleman between Michael and the operative while also relying on the help of Fernando Sucre (Amaury Nolasco), Michael's cellmate at Fox River, to facilitate the breakout. Similar to his first jailbreak, Michael must probe Sona's weaknesses, forge alliances with enemies, and stay one step ahead of personal agendas and unforeseen circumstances that threaten his escape.
