1950s Western starring Rod Cameron and George Montgomery. Tom Horn (Montgomery) is sent undercover by the US Treasury to try and recover the small fortune stolen in a train hold-up by the Hole in the Wall gang. Along the way he teams up with forger Dakota Lil (Marie Windsor) and her associate Vincent (John Emery). Horn understands that saloon owner Harve Logan (Cameron) is connected to the gang, but isn't aware that the ruthless Harve is actually their leader - and capable of convincing Dakota to switch sides and use her forging skills for the gang's benefit. Horn is nothing if not determined, though, and pursues Dakota and Harve in the belief that he can still catch the bad guy and win the girl.
