Miguel, a horribly disfigured young man, goes on a rampage at a masquerade party and rapes and then mutilates a girl. Institutionalized at a mental asylum, he is released five years later, into the care of his sister, Manuela who, along with their wheelchair bound mother operates a boarding school for young women. Miguel becomes obsessed with one of the girls at the school, and wants to resume his incestuous relationship with his sister.
Unfortunately the movie Bloody Moon is not yet available on HBO Max.
