Once inside, the episode shifts from a heist thriller to a gritty, claustrophobic prison drama. The world of Fox River is introduced through a terrifyingly efficient montage: the slamming of steel doors, the catcalls from cellblocks, the shankings in the shower. We meet the key players: the volatile and ruthless gang leader John Abruzzi (Peter Stormare), the deranged child murderer Theodore "T-Bag" Bagwell (Robert Knepper), and the wise old inmate Charles Westmoreland (Muse Watson), who may or may not be the legendary hijacker D.B. Cooper.
