The parents of the young Zhang Jiaze, Zhang Jiacong and Zhang Yanqing were killed by the gangster Snake (played by Kent Tong). The three siblings were living on the streets. Fortunately, the director of the "Children's Home" welfare house (played by Pan Hong) took them in. At Jiaze's insistence, the lovely brothers and sisters were adopted by others. Fifteen years later, Zhang Jiacong (played by Alec Su), who was adopted by a wealthy Taiwanese businessman, has graduated and is engaged to his girlfriend. Jiacong, who changed his name to Zhihua, hopes that his lost brother and sister will be his witnesses at the wedding, and he and his fiancée go south to find his brother and sister.

In order to avenge his parents, he joined Snake's gang. Jiaze didn't want to implicate his brothers and sisters, but Snake took the initiative to find them...
