Young and Dangerous A Wei (played by Tao Dayu) was hunted by the gangsters because he killed the gangster of the gangster boss. He fled to Thailand with his friend Jackson (played by Lee Cansen). There, A Wei met the head-dropping master Chai Wang (played by Yan Qianwen). Chai Wang not only has powerful magic, but also has a secret book that has long been lost, which makes A Wei very jealous. One day, A Wei secretly watched Chai Wang casting spells and learned the fur. It happened that the gangster killer chased him to Thailand. A Wei used the head-dropping technique to kill the killer and save his life. Chai Wang's sister A Shui fell in love with the slick-tongued A Wei, but Chai Wang had long known that A Wei was not a decent person, so he forced A Shui to leave A Wei, which made the latter angry and cast a spell to kill Chai Wang, disfigured A Shui, and took away the secret book and flew away.
