Two riverboat owners staked Maverick $5,000 which he promptly loses to Samantha. Samantha claims Cross is her father and needs the money to get out of jail. Maverick forms a partnership with Samantha and purchases gambling equipment in a scheme to put Joe Riggs, a crooked game room owner, out of business. Samantha and Cross doublecross Maverick by selling the equipment to Riggs.
