Dispatched from Montana to Canada to stop his boss's daughter, Sandra (Gail Davis), from marrying a gold digger (Ross Ford), ranch foreman Gene Autry discovers the would-be bride running a dude ranch and game preserve. But that's the least of his worries when a Mountie gets bumped off, putting the land's ownership at stake and leaving Gene to find the killer. Pat Buttram, Carolina Cotton and Tom London also star.
