The Three Mesquiteers are forced to track down a train robbery ring after some of the gang hijack their truck for a getaway and the police conclude they are part of the gang, an identification which is just fine with the gang's nameless chief.

After being run out of town after town for trying to sell worthless stock, two con artists breeze into the small town of Chesterville, where they find themselves accused of kidnapping a young boy to whom they offered a ride. When that misunderstanding is cleared up, the two conmen hatch a plot to unload all their worthless paper on the gullible citizens of Chesterville.
