Half man, half beast, all horror!
Lucy is a lucha libre (mexican wrestler) who fights her matches in a red devil outfit. One night she injures her opponent Elena and the thought of fighting again upsets her. Happily for her, the cop and boyfriend Arturo is there to calm her and help her through it. Elena gets taken to the local hospital where the brain specialist Dr. Krauman gets called in to help her.
Dr. Krauman and his assistant has recently kidnapped a gorilla from the zoo and are planning to use it for a heart transplant to save his son Julio who are terminally ill. The transplantation does give Julio new life, but also turns him into a half man – half beast. He manages to escape and attacks a woman before being captured by Dr. Krauman.
