Lincoln tries to save LJ and Sara. But he can't. Meanwhile, Michael has a phone conversation with Sara. And Lincoln gets a call from Susan B. saying that she put something in the garage for him.

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).

After the helicopter fails to break out Whistler, Sona's new commander, General Zavala, decides to make Michael talk by putting him into a sun-exposed isolation hot-box. He promises to help in exchange for the truth, verifies the L.J. situation and is told it's about Whistler. Whistler, realizing the tunnel is a no-go without engineer Scofield, denies knowledge blatantly to Zavala and is threatened with torture, until he admits to collaborating with Michael, who convinces him to give up Susan/Gretchen's name. Meanwhile Lincoln, is given a short meet up with L.J. as motivation. Mahone is back in Sona, desperate without his drug. T-Bag and his allies are mainly concerned with Lechero's expected succession and another bare-knuckle fight, won by Bellick. Gretchen recruits Sucre as a double spy (or triple for Linc); then General Zavala arrests and tortures her. Only Whistler's admission makes her admit L.J.'s kidnapping and leads them there, but she manages to kill the General and escape. Michael and Whistler are returned to general population, Mahone and T-Bag join the tunnel escape party. Lechero's cousin Augusto, now calls on Sammy to open the package - a gun.
