Hornblower: The Duchess and the Devil (movie, 1999)

Horatio Homblower, now promoted to Acting Lieutenant, captures the French ship Le Reve off the Spanish coast. The Captain of the French ship is furious that such a youngster has pulled off such a coup. But far more daunting is Hornblower's first taste of the high life, when he is invited to dine with the Governor of Gibraltar and his wife. The prospect of this is frightening enough, but an unexpected guest, the glamorous Duchess of Wharfedale, adds another spin to his evening.
