Ambush Trail from PRC studio has Bob Steele as a young rancher who might have picked the wrong time and place to settle on a ranch he's just bought. The other ranchers in the valley are being starved out by a gang led by perennial western villain I. Stanford Jolley who won't let wagons with supplies get through. Jolley's planning to acquire the whole valley if he can. Why he wants it stays a mystery unless he's just greedy by nature.
Steele is suspected it in the murder of sheriff Henry Hall, but Deputy and brother to sheriff Kermit Maynard trusts him. One look at Jolley's men and I can understand that.
In fact there's a big old surprise waiting for Jolley at the end of the film. He slipped up big time in his scheme though not for lack of trying.
The plot does get a bit confusing, but Ambush Trail holds up well for Bob Steele fans.
