Outlaw Queen (1957)

Christina, the daughter of a Greek-immigrant family who does not share their belief that a woman's place is with her husband at the fireside, is a trick-shot artist, and with her Uncle Jim, a strolling troubadour, and his sidekick Andy, a mandolin player, heads west to make her fortune. Conway, owner of the saloon in a dusty frontier town hires them as performers. Later, she cleans him out in a poker game, with the aid of Uncle Jim calling out Conway's cards in Greek in a song. Chris opens up her own gambling palace, and sends Uncle Jim out looking for a cattle ranch to buy. Conway sends some henchmen over to shoot up her place and she kills one of them in a gun-battle. Meanwhile, out on the open range, Uncle Jim meets Rick Mason, a trail boss for a large herd heading for Dodge City. Chris buys the herd and hires Rick as a foreman of her newly-acquired ranch. Then John Andrews, a mining engineer from her past, comes to town. And Conway is still working for vengeance against her.
