Bret needs a crook alive to clear him of a robbery charge. But Doc Holliday is gunning for the crook, so Bret has to lose to Doc at cards to keep him occupied.

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.
