St. Ives (1998)

In 1813, Capitaine Jacques St. Ives, a Hussar in the Napoleonic wars, is captured and sent to a Scottish prison camp. He's a swashbuckler, so the prison's commander, Major Farquar Bolingbroke Chevening, asks for lessons in communicating with women. Both men have their eyes on the lovely Flora, who resides with her aunt, the iconoclastic and well-traveled Miss Susan Emily Gilcrist. By chance, living close to the camp is Jacques's grandfather and brother, whom Jacques believes died years before. Jacques decides to escape, find his relatives, and win the hand of Flora; Major Chevening and an unforeseen enemy stand in his way. Can Miss Gilcrist contrive to make everything work out?
