after a night of coke and techno music, Alex (Monica Bellucci at her sultry, provocative best) dumps her boyfriend and her ex-boyfriend, leaves on her own, and is brutally raped and beaten in a hellish-looking underpass. After she is taken to a hospital in a coma, the boyfriends vow revenge, which leads them to an S&M gay club, and the rest is… well, that's where the film opens and proceeds in Memento-like reverse-time fashion.
