Bret tries to collect a $10,000 bet from a Virginia City businessman, and ends up killing him in self-defense. The dead man turns up alive and well, and is involved in a scheme to keep an engineer from properly ventilating the Comstock Lode... and reducing the businessman's profits.

A widow hires Bret to escort her--and her $200,000--to a Montana town. Bret soon finds himself on the run with the $200,000... which is counterfeit.
