Tom Paxton, a Company agent, is dispatched on a mission into Fox River Penitentiary after Michael Scofield, an engineer with no previous criminal record, suddenly attempts a bank robbery and is sent there. In this same prison, Scofield’s brother, Lincoln Burrows, is set to be executed for the murder of the Vice President’s brother. Paxton’s orders are clear: observe Scofield and find out what he’s up to. Paxton must adapt to prison life and remain inconspicuous while maintaining his undercover status. But prison has its rules and regulations, as Paxton quickly — and often painfully — learns while digging up information about the key figures in Fox River and their plans. Suddenly, the mission becomes more than simple observation: it’s a deadly game, and survival is the main goal — and the ultimate prize.
