In 1950's Westburn, Scotland, Tim Ronsard only has a few months remaining until he leaves St. Mary's School.
Bored and listless, he's anxious to get away. His life changes when a new music teacher is appointed: Isobel Clieshman, a Protestant working in a Catholic school. Soon, Tim's feelings go well beyond a school boy crush, but at 23 years old the teacher is out of his reach.
Five years later, they meet randomly and soon, Tim thinks he has never been happier. But amid family issues, war and prejudice, can they find the road to happiness together?
