The neologistic title of this film translates as "Death Bureau," a secret vigilante organization used by ordinary working folk to rid the city of criminals through secret executions. Woodworker Leo Stoychev goes to the organization for help because his boss Branco won't repay a loan and may have had something to do with the accident that crippled Leo. The Mordbüro is responsible for the death of a crooked lawyer, and Inspector Raoul becomes suspicious.
