Reversal of Fortune is a 2003 South Korean film directed by Park Yong-woon, and starring Kim Seung-woo and Ha Ji-won. The film features several songs from Ha Ji-won's debut album, Homerun.
Having turned his back on a promising career as a professional golfer, Kang Seung-wan is now a down on his luck stock exchange worker, and in debt to local gangster Ma Kang-sung. After crashing his car while driving through a tunnel, Seung-wan wakes up to find himself in an alternate reality where he fulfilled his sporting ambitions, and is now a famous golf champion. But things aren't as perfect as they first seem; he now has a wife who wants a divorce, and must compete in a major golf tournament despite not having played for over ten years.
