Synopsis: "Gentleman" Tim Madigan (Tim McCoy) is a dapper card shark who plays for big money in cowboy saloons from Nevada to California. Despite his big black hat and bow tie, "Gentleman" Tim never wears a gun.
In one high stakes game, Jose Hernandez, the son of a respected Mexican rancher, loses a bundle until Madigan exposes the opponent as a card cheat and returns the boy's money. Later, the crooked player is found murdered. The local sheriff suspects that Jose is the killer but also keeps a close eye on Tim. While fighting to avoid arrest, Madigan struggles to save the Hernandez ranch from the creditors.
