They Made Me a Fugitive

They Made Me a Fugitive released in the US as I Became a Criminal is a 1947 British film noir set in postwar England.

Clem Morgan, demobilised from the Royal Air Force and unemployed after the war, is drawn into the world of crime. His psychopathic crime boss Narcy short for Narcissus deals in the black market, transporting goods in coffins to his headquarters in a funeral parlour. Clem finds the activity harmless enough, until one day he finds drugs in the latest coffin. Clem objects and tells his girlfriend that he will quit after one last job that night, the looting of a warehouse. Narcy betrays him, triggering the burglar alarm while he is inside. Clem manages to get back in the car before his associates drive off. When Narcy orders the driver to run down a policeman, Clem grabs the wheel in an unsuccessful attempt to save the mans life and the car crashes into a lamppost. Narcy knocks him unconscious and has him moved to the drivers seat before fleeing.
