Heading the cowgirls are Patty Andrews, Maxene Andrews, Laverne Andrews, Lou Ferguson (Elyse Knox) and Abigail (Minerva Urecal). Lou tells Tom that a large number of cattle have been mysteriously disappearing, and they decide to hire neighboring rancher Pasqualito (Leo Carrillo), who makes claims to being a great detective, and his assistant, Ogala (Frank Lackteen), an Indian. Tom’s cattle show up on Pasqualito’s ranchero, but he has an excuse.
