Tonton Film The Vengeful Beauty (Xue fu rong) (1978)

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, 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. Qui-yan is forced to go into hiding as she plots her revenge and finds allies in fellow fugitive Ma Seng and ex-lover Wang-jun.
