Despite its stand-alone title, this mixture of martial arts and exploitation is a semi-sequel to Shaw Brothers’s Flying Guillotine series. This time, the focus is Rong Qui-yan (Chen Ping), a kung fu student turned dutiful wife whose life falls apart when her husband is murdered by a squad of government operatives led by the duplicitous Jin Gang-Feng (Lo Lieh). Qui-yan is forced to go into hiding as she plots her revenge and finds allies in fellow fugitive Ma Seng (Tsui Siu Keung) and ex-lover Wang-jun (Yueh Hua). Meanwhile, Jin Gang-Feng sends out an array of killers to track them down. Complicating things further is the fact that Qui-yan is pregnant and struggling to keep her unborn child safe while fighting her way to safety.

He fights evil, saves damsels in distress (including a kindhearted prostitute played by Chow Yun-fat’s first wife, Yu An-an), and duels rival swordsmen to the, well, death.
