Back at the yacht, Michael notices Lincoln is gone and calls him. Alex Mahone tells him Linc is no cold-blooded killer, so he was overpowered and hand-cuffed, and the ransom is the yacht and the fortune he assumes to be in it, to be agreed in five minutes. Now Mahone is even more wanted than the brothers. Kellerman's self-incriminating testimony and documents he brings get all charges against Sarah and Lincoln dropped, him arrested. Mahone calls Kim to fly over immediately. Alex calls his wife, to make her bring the kids for a holiday in her native Colombia, at Cartegena. Despite 30% blood-loss Fernado leaves hospital to report missing Bellick, who is already in jail and gets T-bag's company. Vendor Chaco gets Michael introduced to a local yacht owner to whom he suggests collecting the $100,000 reward on his head, then makes a better offer. Mahone called the police intending to frame the brothers for his intended murder on 'an Asian', but Michael refuses to hand over the money and Kim turns up early, with armed back-up. Mahone runs but is arrested. Kellerman knows the situation he is involved in and expects to be assassinated so his transport to prison is arranged to get car trouble and a masked man shoots him. Chaco delivers to the brothers, who got away with the money and intended to run and never look back, a crummy boat with a priceless surprise: Sarah and the great news for Linc, with good hope for Michael. Just then Kim turns up, refuses the money, aims at Linc and is shot by Sarah. Police arrive, chasing and trapping the trio. Michael takes the gun and pretends to take Sarah hostage, then lets himself be arrested and locked up in Sona. Malone calls his wife to forget he ever existed- from jail. T-bag expected to be released as agreed reward for baiting the brothers, but the man he hoped to bring him the good news says getting caught broke the deal.

Michael is once again imprisoned, but now in SONA (Panama), together with T-Bag, Mahone and Bellick. The prison is solely ruled by inmates, whose local prison-lord Lechero feels threatened by Scofield's 'fame'. Lincoln tries legal means to get Michael transferred, and gets a call from a relative. Both receive the same message, through different channels, from The Company.

After Michael gets bad news from Lincoln, he sets out to find a prisoner named James Whistler, who holds the key to his freedom. That's easier said than done: James Whistler is hiding in Sona because there's a price on his head, and Lechero is not about to help Michael find him. In addition, both Mahone and Bellick want to get to Whistler too. Meanwhile, T-Bag won't allow a little humiliation stop him from insinuating himself into Lechero's good graces.

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.

Lincoln tells Michael that they have four more days to rescue Whistler, but Michael is upset with his brother that he used him. Gretchen has a meeting with General and they decide to use power to release Whistler in an operation called "Bang and Burn". Later she asks Whistler to kill Michael. In Sona, the guards reinforce the bars in the windows, and Michael tells Lechero that this way it will be difficult to break-out. Sammy requests more men to Lechero to keep Sona under control. Sofia receives a call from Whistler's mysterious landlord telling that he has some "insurance papers" from her boyfriend, however, the Company intercepts the conversation. When Sofia receives the documents, she finds a passport of Whistler in the name of Gary Miller. But Gretchen arrives and takes the documents. Mahone tells Agent Lang how he killed Shales and then high from the pills, asks her to get some drugs for him otherwise he will not be able to speak in the hearing. T-Bag gives a message from Lechero with the blueprint of his cell with a hidden door and an access code. Whistler is ready to stab Michael when Lechero arrives and he hides the knife. Michael asks McGrady to request his father to call Lincoln and give him a message: "Don't come home for dinner." Mahone fails in the hearing and is sent back to Sona. Lincoln, Sucre and Sofia are attacked by the Company's agents and the brothers realize that something is happening, i.e., the Company does not need them anymore. When the "Bang and Burn" Operation begins, Michael catches Whistler and Gretchen fails in her intent. General Zavala has Michael hauled in for questioning over the attempted breakout.
