One night, a woman factory worker (Chen Ping, in her first Shaw film) is gang-raped on her way home from work, contracts an STD (the aforementioned "Vietnam Rose"), and decides to get back at all the perpetrators before the disease claims her life. She learns how to be on the offensive from her new employer--and eventual lover--a club owner (Lo Lieh) and a fellow employee (Hui Siu-Hung).
