The holdup of the bank is a success. All happened according to plan. Now, Cyril Gad and his four accomplices must secure an alibi. What better place than a prison cell? As a result the five gangsters have themselves arrested on minor charges and start waiting until they are released. Unfortunately three of them die mysteriously, another one is openly murdered. The only man still alive, Tony, is scared. Easy to understand why...
