Ballad for a Hoodlum (1963)

Vincent Vivant agrees spy Stephan's proposal: to cross a border with a suitcase containing a very special thing. And of course he must not open this piece of luggage for it might explode and make mincemeat of him. He needs money to leave for a foreign country with his lover Martha. His partner Molok is in charge of doing away with him when the job is done. But Vincent discovers this and kills him. Now the young man is pursued by the police and Stephan's sidekicks.
