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.

Constantly mistreated by her cruel, alcoholic husband Chun-yu (Wang Jung), frail Chan Sau-ying (Tanny Tien Ni) awaits certain death from tuberculosis. New servant girl Yi-wah (Chen Szu-chia) takes pity on her mistress’ plight but, after suffering Chun-yu’s abuse once too often, the pair proceed to drown him one evening. They dump his body in a near-by pond but Sau-ying believes that the man’s bloated corpse has risen from the bog to seek vengeance. Yi-wah dismisses her claims as the delusions brought about by guilt and her illness but it appears that the house is indeed being haunted by a corpse that will not be easily appeased.
