Postal inspector Winters has infiltrated a criminal gang and their big plan is about to go down. A postal employee drops a $120,000 in bonds out a back window to Winters waiting in an alley. Needing time to switch the real bonds with phonies, he makes up a story about being robbed and knocked unconscious. The boss, Cruze is not amused and gives Winters two hours to find the bonds and bring them back, or be rubbed out.
