Texas Ranger Johnny Mack Brown (Johnny Mack Brown) is assigned to apprehend Walt Winslow (Dale Van Sickel), an escaped convict imprisoned for a $100,000 express robbery, from which the loot was never recovered. Brown finds him in fatally wounded in a stagecoach holdup by members of his former gang. Before he dies, he whispers something about "a pick' to Brown. Walt's honest brother, Dan Winslow ('James Ellison')is working in a bank in a nearby town. Mrs. Amelia Winslow (Barbara Woodell) arrives in town with a crude oil painting done by Walt. Kelvin (Terry Frost), a crooked deputy sheriff, frames Dan into giving the gang the combination to the safe, and the Sheriff (I. Stanford Jolley), is slain and Dan is jailed as a suspect. Then all involved realize that Walt was trying to say "a picture" as the clue to where the $1000,000 is buried.
