An employee interrupts a burglary at a bank and is killed. When nothing is found missing, it is assumed the burglars panicked and ran. Months later when a cashier notices two bills with the same serial number, Slade is called in.

Slade catches up with Frank Galt, a man he has been trailing. The man has been leading a five-man gang through a string of bank robberies. Slade gets him to jail but must now convince the man's ex-girlfriend to testify against him.
