A child of the 60's, baby Tommy was accidentally left behind at a wild London party by his incredibly wealthy parents, only to be raised by a poor Pakistani family, the Patels, as one their own. Now grown up, the unlucky soul discovers to his horrors that not only is the real 15th Duke of Bournemouth, but that his ne'er-do-well American cousin Henry has inherited everything, including the title and vast fortune, that should be his. To make matters worse, Tommy's real mother, the Duchess Lucinda, unknowingly tries to seduce him - her own son! - while the girl of his dreams, the beautiful and mischeous Kitty, wants only to marry Henry. What's a young, greedy, poor (but really rich), desperate chap to do?
