With tensions already high, Emma is thrown into a tailspin when her creepy foster brother, Travis (recurring guest star KENNETH MILLER), shows up. Seeing he has an upper hand with Emma, Travis decides to use his knowledge of Emma's situation to his benefit. With her relationship with Ethan still strained, she has no one to turn to and is forced to go along with Travis's plan if she has any hope of getting him to leave her alone. But with her old life looming over her, will this be the straw that breaks Emma's back? Meanwhile, Sutton is forced into Emma's life when she is sent back to Las Vegas.

Abruzzi, Sucre and C-Note make a run for it on their own; Michael and Lincoln plan another breakout – this time to rescue a jailed LJ, whom Mahone targets in his quest to capture the escaped cons; Bellick and Warden Pope face a jury of their peers regarding the prison escape; Tweener hitches a ride with the college crowd; and T-Bag takes drastic measures to get the upper hand.
