A test with a rat proves the tower snipers are very good, so Michael figures the only option to breaking Whistler out within 24 hours has to be at 3 PM, during the distraction of soccer game. Sucre accepts $5,000 from Lechero's cousin, Augusto, to smuggle a package into Sona. Linc is to arrange transport outside, but he and Sofia get turned away roughly by an army patrol two miles away. He tells her Sara has already been killed. He keeps it from Michael, as LJ is his ultimate priority. New prisoner Andrew Tyge is robbed to his boxers on arrival, and recognizes Whistler (who denies it), mentioning the McFadden, Nice in 1997. He is warned off by Mahone who has noticed Tyge snooping around Michael and Whistler. They plan an electric signal disturbance device to distract the guard tower. Before they can make a move, a reflection from the binoculars is spotted: the troops move in and find it in his cell. Michael admits it's his. When the commander is about to shoot him, Whistler claims it's his for bird-watching, and proves it showing the ornithology book (the one Linc couldn't hold on to).

Tyge tells Michael that he and Whistler were co-employees at the McFadden, a hotel in Nice, France. Mahone worries about Tyge's constant, keen observance of Whistler. Having to re-plan hastily, Michael tells Linc to find out the location of the nearby cafe and drug the guard's coffee, and also demands pictures of LJ and Sara before he escapes. Tyge is stabbed to death. Lechero questions McGrady and has Whistler dragged away for a confession. Michael believes Mahone and Bellick's denials. T-Bag offers Michael a ring he stole from Sammy (his rival for Lechero's confidence), to use to frame Sammy for Tyge's stabbing. Michael finds the murder knife under Mahone's bed and goes to Lechero to denounce Mahone, only to find he has just walked out of the prison. Agents Richard Sullins and Felicia Lang arrive at Sona to present Mahone with a plea bargain from the US Justice: a term reduction to 8 years for testimony against the government conspiracy and Lincoln. He could be out in 4 years, but Mahone refuses, now he faces life imprisonment. Lechero administers justice for Tyge his own way. Linc and Sofia succeed in drugging Captain Hurtado, but Susan finds out the brothers had a different timing planned and threatens LJ's life. With no recent pictures available, Linc confesses Sara's death, causing Michael to make a drastic decision.

Mahone is assured all he has to do is tell the truth, enjoying full immunity. Michael tells Whistler their row is part of a diversion, the escape is now or never, before the drug in the guard's coffee wears off. Just when the critical sun reflection blinds the other tower guard, they must wait and hide till Sammy has passed, but get through the cut bars. They climb down, but the glare disappears so they must climb back up as there is not enough time to escape. They get back in time and out to the courtyard, but Lechero refuses to allow them to cancel their duel to the death in the courtyard, which had been intended as a fake diversion. Sofia draws a gun on Lincoln to prevent him from turning Whistler over to killers. He retorts that's condemning an innocent L.J. to death. Guards wake the passed-out Captain Hurtado, see the climbing rope and storm into the prison. The Colonel shoots Papo, one of Lechero's crew, 'for not telling' and exposes his deal with Lechero, questioning if he's the right man for the job. Hearing the Sona siren, Linc flees by car and when Susan calls, he lies, telling her he has the 'escapees' in the trunk, but Pike, another company operative phones her: the roll-count was complete. Sucre stops her van by crashing into it, but even when Linc holds her at gun-point her accomplice won't trade L.J. He releases her and gets a short extension to find out what happened. Failing a hearing, Malone now believes Justice official Richard Sullins is setting him up to confess. Michael is dragged before Lechero, but not to be punished, he's ordered to take the fallen boss along when he and Whistler escape. Susan asks instructions from Whistler, he tells her - as Gretchen - to give the brothers four more days.
