Guy works hard, wrangling both cattle and tourists for a Wyoming dude ranch. The problem? He's a bit lonely, and figuring he hasn’t got many good years left in him for finding someone.
That's when AJ shows up. He's a young veteranarian, taking over practice for the old doc who's fleeing to Florida to warm his old bones. Turns out to be the best thing that could have happened to all of them, inclosing the menagerie of strays AJ takes in after he arrives.
The two get to know each other, get to liking each other, going from friendship to a little sweet romance just in time for winter. Just in time for Guy to figure he's not so old after all. Just in time to keep each other warm for in the place they've made with each other, menagerie and all.
