Synopsis: Having seen her father, Tim, killed by enforcers working for greedy miner Robert Weylan, plucky Shirley Martin takes control of her family's cattle farm. Though he has no legal right to do so, Weylan and his men have been chasing Shirley's animals away from a local river. With backing from experienced ranch hand Bob Lawson, Shirley intends to win this standoff, save her business and prove her mettle in a male-dominated culture.
