Not my usual cup-of-tea, but an interesting unusual noirish drama thriller. Made in 1961 by Gene Corman, the story is about a cat burglar who unknowingly steals important papers that thuggish traitors are hot after. At one-point the thugs beat up the burglar, a rather unpleasant scene. Also involved is an innocent secretary who was used, for her part unknowingly, as a courier. She displays an interest in the burglar. A more unlikely pair I can't imagine. In the end the burglar develops some patriotism and foils the bad guys. A downer, but not unexpected ending.
