'The Wolf Behind the Door') is a 2013 Brazilian thriller drama film written and directed by Fernando Coimbra, in his feature directorial debut.

At first, she is reluctant to speak, and tells the police that she was blackmailed into taking the girl at the behest of a woman named Bete, whose husband was supposedly involved in an affair with Sylvia.

She tells him that she does not mind being his lover for the time being, but begins to visit his wife and child, befriending her by pretending to be a mutual acquaintance of an old friend and presenting his daughter with gifts.

She picks up Clara at school, and eventually takes her to an abandoned lot, where she pulls out a pistol from her purse, kills the child, and burns her corpse with flammable liquid.

The film ends with a voiceover from the police officer describing Rosa's statement about the matter: she feels no remorse, and understands the full weight of her actions.
