Small-time criminal Cooper manages several warehouses in Los Angeles that the mob use to stash their stolen goods. Known as “the key man” for the key chain he always keeps on his person that can unlock all the warehouses, Cooper is assigned by the local syndicate to negotiate a deal for a new warehouse because the mob has run out of storage space. However, Cooper’s superior Carl gets nervous and decides to have cocky cowboy button man Turner keep an eye on Cooper.
