Magnum, P.I. S07E17 - Forty

Magnum is in Chinatown with Rick and T.C. celebrating his upcoming fortieth birthday, but he has little to celebrate when he loses his lucky $2 bill that his grandfather gave him as a boy. While looking for it, he by chance briefly meets a beautiful woman. He also winds up helping an old friend who is one of a number of shopkeepers being terrorized by an organized gang. The case takes a backseat as he becomes preoccupied with the woman only for it to seem that she is tied up with the gang he is supposed to be investigating, in a situation that sees him losing more than just his lucky bill.
