Cattleman J.G. Whittemore, owner of the Flying U ranch in Montana, trusts the task of meeting his sister at the train to only one man, Chip. Chip’s not too keen on women. In his experience they come in only a few types: prissy “sweet young thing”, annoying cowgirl, or old maid that wants to drag him to church. He isn’t prepared for Miss Della Whittemore, the “Little Doctor.” She turns the ranch upside down, but can she turn Chip head over heels?
