Silly Billies (1936)

"Folks, It's a MASSACRE! The "Cuckoos" Are on the Run..and Are the Indians Wild?"

The boys are a dentist and his assistant traveling to the Old West to open a new practice. Once in town, they buy a business--only to wake up the next day and see that the entire population of this bustling town had left for the California gold fields early that morning! Then, they discover an evil plot to sell out these settlers to some hostile Indians, so they spring to the rescue.
