In this prison drama, Franz Blum (Jurgen Prochnow) goes from being a fairly ordinary middle-class man to a hardened convict. Sent to prison for participating in a bank robbery, he learns how to use blackmail and graft in order to survive the harsh life he encounters "inside." The screenplay was written by ex-prisoner Burkhard Driest (who plays a prison bully in the movie), and is based on his own experiences.
