S03E11: 'Under & Out'

Scofield and his crew decide that they must break out later that night because of the heavy rainfall's damaging effect on the tunnel. He is visited by his brother at Sona, with the pair discussing how Burrows can distract the guards on the outside.

Scofield believes that the key to escape lies in cutting off the power at Sona, and Sucre returns to his gravedigger role in order to have access to the generator.

Before Sucre goes to Sona, he meets with Susan. She again threatens both him and Maricruz and reveals that she found the car bomb. Sucre buckles and confesses that the escape has been moved forward to later that evening, although Burrows later calls and tells her also.

Sofia and Burrows are taken by Susan, who calls Whistler and tortures his girlfriend with a lit cigar in a bid to find out the coordinates she is after. Whistler doesn't give in though, later telling Susan to her face, when she visits Sona, that he will only comply once everyone is safe.

Sucre sabotages the patrol jeeps, but when the escape is about to happen T-Bag and Lechero put a knife to Whistler's throat and demand that they go out first - as there is only 30 seconds when the power will all be down. Meanwhile, Burrows steals a bus and ploughs it into an electricity pole outside Sona.
