Michael Scofield intentionally gets himself incarcerated in order to use his skills as a structural engineer to break his brother Lincoln Burrows out of death row.

A failed rescue attempt deeply affects the men and women of Firehouse 51; Dawson and Shay deal with a drug-user's erratic behaviour during a call, and the team upset local drug dealers.

Casey must work with Voight and the Intelligence Unit; Shay grows increasingly excited about motherhood; the house come together to support the opening of Molly's.

Michael looks to his fellow prison mates to help formulate his escape plan; Lincoln and C-Note go on a hunt for the `Sheik of Light'.

Pressed for time, Michael tries to enlist the help of his cell mate, who asks for a transfer when he realises what Michael is planning to do.

In the wake of Sara's shooting, the two families must confront the decisions they've made up to that point, and look to what the future will hold.
