Crime story dealing with safe-breakers and gang warfare.

A gang of thieves led by American Eddy (Reed de Rouen) kill a security guard during a botched safe robbery and flee with his daughter (Leigh Madison) as a hostage. They hide out in a dangerously unstable old warehouse for a couple of days awaiting their getaway ship to sail, but Johnny (Kenneth Cope) falls for the girl - provoking a serious falling-out and a violent conclusion to the disastrous heist.

The cat and mouse game between government agents and a spy ring that has taken secret documents from a plane crash in Germany, not far from an US military research centre.
