An adult brother (Diego Gamaliel) and sister (Mar?a Evoli) find shelter in a slovenly apartment belonging to a charming madman (No? Hern?ndez). They accept his offer to stay in his filthy abode, but it also means submitting to his explorations into perversity -- including murder, incest, and cannibalism. Slowly, with hypnotic gusto, they become willing participants in a journey into the far reaches of bodily sensuality.
