Larry Day (Fred Humes), a hard-working honest foreman of an Arizona ranch, is in love with Kathleen Cosgrove (Margaret Gray), the ranch-owner's daughter. John Cosgrove (George B. French), the ranch owner, sells some of his stock to Mel Craven (Cuyler Supplee), a crook who plans to get his money back by plotting with Tom Day (Fred Humes), a cousin of Larry's known as "The Night Hawk." The plan is to get Larry away from the ranch and hold him prisoner, while Tom, who is an exact double, takes his place and goes back to the ranch. The plan is working to perfection but just when Tom thinks he has everything going his way he is frustrated by a monkey, a pet of one the ranch cowboys. And Larry has escaped and on his way back to the ranch.
