 Pa Jackson (Stanley Andrews) and his sons, Shag (Pat Henning) and Ben (Matty Roubert), come to the Milt Brower (William Farnum)-Roy Rogers (Roy Rogers) ranch while Roy, Claire Brower (Lynne Roberts as Mary Hart), the ranch hands and Lulu Belle (Myrtle Wiseman) and Scotty (Scott Wiseman)are attending a dance. Jackson wants Brower, his former partner, to join with him on the formation of a rustling gang, since the Brower-Rogers ranch is the gateway to a high granite range accessible by only one pass, and by the time a posse could travel the hundred miles to the other end of the pass, the cattle could be moved and sold. Brower declines, but the granite range becomes known as Jackson s Hole as Jackson and his sons and gang rustle cattle unchecked. Homer Sheldon (Frank Jaquet), president of the Stockmen s Bank, accuses Brower of informing Jackson when and where to strike.
