This just might be the most demented film of all time, shocking even by Hong Kong's outlandish standards. Lily Chung plays an abused teenage girl suspected of killing her tormentors. But apparently because ''Daughter of Darkness'' is set in mainland China, the cops investigating the crime (led by Anthony Wong) show absolutely no compassion for the poor girl. And neither does the film, playing everything for laughs and succeeding brilliantly. It features the most unbelievable sex torture scene ever filmed. Directed by Ivan Lai, this violent story of sex abuse and murder is one of the best sexploatation films ever made: perverse, gory, kinky and very shocking. To quote a reviewer, M.C.Thomason, ''if you have a strong stomach and are open-minded enough to comprehend another culture's attitudes towards screen violence, then "Daughter Of Darkness" is definitely one of the unsung gems of Hong Kong's adult-horror industry. Just don't blame me if it offends you in the extreme!''.
