LET'S BE HAPPY (1957)

On receiving an inheritance from her grandfather, Canadian Jeannie MacLean decides to visit the family's Scottish roots. On the plane she meets businessman Stanley Smith, and romance blossoms in Edinburgh. The complications begin when Stanley breaks a date with Jeannie to woo voluptuous redhead Helene, and Jeannie is flattered by the attentions of the impoverished Lord McNairn; he's heard about her good fortune, and gallantly offers to show her the city.
