 Ranchers Ted and Harry Johnson are openly disdainful of George Wilson, their sister Iris s new city-bred husband who lives on their ranch. George and Iris argue about the situation and Iris is critically shot and wounded when she foolishly tosses a loaded revolver in George s direction. George panics and flees, but quick-tempered Ted Johnson is determined to extract revenge for his sister s (presumed) death and goes after George with a rifle. Iris subsequently survives an emergency operation and weakly admits that the shooting was an accident. Given this information, Dan Mathews uses the Highway Patrol helicopter for an all-out effort to locate George Wilson and Ted Johnson in the rough terrain before a fatal tragedy occurs.
