Gold and the Girl

Dan Prentiss, the special undercover agent of a mining company, is assigned to investigate a series of robberies involving gold shipments. He earns the friendship of Ann Donald by saving her life when her horse is frightened by his dog, Pal. Dan also meets both Ann's uncle, Sam, and his partner, Colton, who is one of Ann's suitors. Dan finally decides to trap the unknown robbers by driving the truck carrying the gold shipment himself. After he sets out on this perilous journey, Ann discovers that her uncle and Colton are the bandits and sets out to warn Dan. The sheriff's posse captures all of Sam's gang except Sam and Colton, who head for the hills. Dan tails them and captures Colton; wounded by the posse, Sam kills himself to avoid capture. Ann promises to wait for Buck, who plans to return for her as soon as his work permits.
