If your brother goes to death row without committing a crime, would you sacrifice your freedom and get locked in too so you could help him escape? Many of us would probably say no.
Michael Scofield is different. An intelligent structural engineer, he creates a very detailed escape plan, then robs a bank and asks the judge that he be incarcerated in the prison where his brother is jailed. Tattoos play an important part in his plan. The map of the prison–as well as other details needed in the escape–is tattooed in his upper body. When he gets into prison, his Prison Break adventures start.
Micheal is a TV character, by the way. He is played by actor Wentworth Miller in the hit TV series Prison Break, which is now in its second season in the United States.
