Criminal Lovers(1999)

After a perverted impulse drives them to kill, Alice and her boyfriend, Luc, drag the body into the woods, only to find themselves hopelessly lost – much like the fairy-tale plight of Hansel and Gretel. Starving and with no hope of being found, they chance upon a dilapidated cottage where a hulking man takes them prisoner and proceeds to feed Luc's sexual appetite.
