Inspired by a true story. A petty criminal sent to Alcatraz in the 1930s is caught attempting to make an escape. As punishment he is put in solitary confinement. The maximum stay is supposed to be 19 days, but Henri spends years alone, cold and in complete darkness, only to emerge a madman and soon to be a murderer. The story follows a rookie lawyer attempting to prove that Alcatraz was to blame.
Three detectives in the corrupt and brutal L.A. police force of the 1950s use differing methods to uncover a conspiracy behind the shotgun slayings of the patrons at an all-night diner.
