Sam McMahon can’t understand why his banker colleagues in Toronto keep calling him “cowboy,” when he prefers opera to C&W and fine wine to beer. Sam’s wife is in love with his brother Vern, who has followed the family tradition and works their parents’ farm, a mixed cattle and crop operation inherited from his grandfather, Old Sam. When his wife leaves him stranded by the side of a Saskatchewan highway, Sam is rescued by a woman, Ai Lee, in a rented Toyota.
