Prison Break began in 2005 and tracked the story of Scofield who gets himself imprisoned with the intention of breaking out his innocent brother, Lincoln (Dominic Purcell).
The show ran for four seasons before the axe fell; a supposed swansong arriving in the form of a wrap-up TV movie titled The Final Break in 2009.
