Cannibal

Carlos (Antonio de la Torre) is a soft-spoken tailor that hides a secret double life as a serial killer. He stalks his prey carefully and carts them off to a remote mountain cabin where he slices them up and takes a bit of their meat home with him to devour later at his convenience. Carlos otherwise lives his life uneventfully until his path crosses with the beautiful Alexandra (Olimpia Melinte), who tries to spark off a relationship with him. 

Shortly thereafter, Alexandra goes missing and Carlos is contacted by Alexandra's twin sister Nina (also played by Melinte), who believes that Alexandra ran off after stealing money from their parents. Carlos offers to help Nina to a degree that makes her instantly suspicious, but she decides to stay with him because Alexandra's brutish boyfriend is causing trouble. As the film progresses, Carlos finds himself becoming drawn to Nina and eventually he offers to take her to his remote cabin. He decides that he will drug and murder her, but finds himself incapable of performing the task. 

Carlos tries to confess that he's murdered not only Nina's sister, but also multiple other women and was going to murder Nina as well, but she refuses to believe him. However, as they drive down the mountainside together, Nina deliberately causes a car accident in order to kill them both.
