The Falcon (George Sanders) finds himself embroiled in a murder when ex-jailbird Moose Malloy (Ward Bond) storms into a nightclub looking for his former showgirl girlfriend, Velma. When the manager refuses to tell Moose where she lives, Moose kills him. The police swarm the nightclub and begin to question the witnesses but the Falcon decides to carry out his own investigation. Things grow a little more complicated though when the Falcon is hired by Marriot (Hans Conreil) to make a $10,000 pay-off in return for a stolen jade necklace. When the assignment turns out to be a trap, the Falcon finds himself in the middle of a deadly game of cat and mouse.
