Bat agrees to work undercover for the Wyoming territorial administrator to try to infiltrate a gang of ruthless Cheyenne businessmen who mastermind a crime wave behind their veneer of respectability. Bat works his way into their gang by joining a poker game with them at the Cheyenne Club, losing over $10,000, and then not being able to pay. To make good on his debt they force him to help organize the robbery of a bank one of them manages. Bat puts together two plans. One is how to rob the bank and the other is a frame up of the bank owner. He enlists the aid of a female blackjack dealer Ellie Winters he asked to join him in Cheyenne. They discover that federal agents are there who suspect him of complicity in the crimes as they know nothing of his assignment. Ellie sees an article in the paper that his alibi, the territorial representative, died of a massive heart attack, leaving him trapped between two fires. Written by
