Hong Kong

After the Gls quit Indochina, a new ar breaks out between the drug traffickers and white slavers. Bill [RON VAN CLIFF], a black American Kung Fu expert, is sent by Interpol to investigate. A pretty Thai girl, Ellisin, is sold in Hong Kong to a young labourer, Chan [CARTER WONG], whose hobby is Chinese Kung Fu. Forced by the drug syndicate to act as courier, she is rescued by Bill who brings her to Bangkok to trap the big boss. There Bill meets Ellisin's Thai Boxer-brother Ichai, whose identity is unknown to him. When Ellisin is captured by the gang, Chan follows her to Bangkok where he joins up with Bill and Ichai to rescue his wife. Bill survives many attempts on his life before he brings the gang leader, Smith, and his hired killers to justice.
