Felon (2008)

Wade Porter (Stephen Dorff), a loving father of the family with a promising future, suddenly loses everything when accidentally kills a thief who came into his house. Convicted of manslaughter, Wade is sentenced to spend the next three years in a maximum security prison where the rules of society do not apply. Forced to share his cell with a notorious killer (Val Kilmer) and subjected to brutal beatings orchestrated by the sadistic head of the prison guards (Harold Perrineau), Wade soon realizes that will have to face the fight of his life and needs to pay the hardest if you want to survive the prison at the time of conviction. What does not kill makes strong. And in prison, only the strongest survive.
A good film that portrays the life of a high security prison in the United States. I like Val Kilmer’s interpretation of that is almost unrecognizable in this film.
