Where to Watch Mad Mask

A bartender, a serial killer who skins his face and wears it like a mask after killing a guest. One day, he runs into a suspicious man drinking alone at a bar. After killing him and wearing his face like a mask, the bartender soon becomes engulfed in a nightmare fantasy. In the fantasy, he encounters himself, who is much more cruel and bizarre than usual, and finds out that the man is a much crazier man than he is. His face clings to his skin of a bartender, and his madness is at its peak.
