In director Ho-Cheung Pang's black comedy, Sgt. Tsim Kin-Yip (Simon Yam) interrogates Kwan (Nick Cheung), a pervert picked up for peeping in a women's restroom. Kwan claims he was only there to gather evidence about a secret clan of women conspiring to rid the world of men. The detective dismisses Kwan's wild story as the paranoid ravings of a lunatic, until mounting evidence to the contrary becomes too difficult to ignore.
