It's 1893 and gold is being smuggled out of the country. Instead of stealing gold bars, the outlaws are stealing high grade ore, having it smelted, and then having it plated to look like lead. The Government sends agents Bret (George Montgomery (actor)) and Larry (Jerome Courtland) who arrive in Cripple Creek posing as Texas gunfighters. While their partner, Strap (Richard Egan (actor)) works on the inside as an informant, Bret finds the smelting operation and Larry learns of the payoff. The crooked town Marshal is suspicious of the two men. The reply of his inquiry to Texas exposes them, putting their lives in danger.
