Guarda su Altadefinizione. Three men plot to assassinate the dictator of their country, but their plan fails and one of them is captured and imprisoned. Even after considerable torture and interrogation, the revolutionary maintains his silence as to the names of his accomplices. Soon he is killed, though no one seems to know who is responsible for his death. Four years later another regime has been established, and a former inmate of the dead revolutionary finds himself in a position of power. He now intends to find out who was responsible for the man's death. After this German tale first took the form of a radio play and then a stage production, character actor Peter Carsten decided to produce this film version.
