No es bueno que el hombre esté solo (1973)

Resident in an industrial city, Martín is a lonely man who lives isolated in his villa where he has created a world of his own that he shares with Elena, a doll he treats as if she were his wife. In a neighboring apartment lives Lina, a prostitute, and her daughter Cati, an overly curious girl who discovers the truth. Little by little, Martín will be dominated by Lina, to the point that she and her daughter settle in his house. Mauro, a pimp and Lina's lover, will precipitate the tragedy with his aggressive behavior.
