In the town of Epitaph, owned by Epitaph Mines, agents James West and Artemus Gordon arrest Norbert Plank, chief bookkeeper for the powerful syndicate that owns the mining company. Through Plank, the agents hope to get their hands on records that could build a case against the organization. The whole town turns out to free Plank, whom West has hidden in a church bell tower, while Gordon masquerades as lay-preacher Hallelujah Harry. Gordon hopes to get to the head of the syndicate, Diamond Dave Desmond, and walk off with the ledgers. But Diamond Dave's girlfriend, Rhoda, has the same idea and blackmail on her mind.
