Glass Lips (2007)

Comprised of a series of shots that tell three separate story-lines that are somewhat interwoven. The two main characters are a father and his son, and the mother plays a cursory role. In the beginning of the film, we see the son - who later becomes admitted in a mental institution - being tortured by his parents for misbehaving. Instead of getting a whipping after spilling liquid at the dinner table, he has a belt tied around his neck and is forced to drink his soup like a dog. We later see that the dad is dysfunctional himself, and tortures himself in the same ways that he had once tortured his son. It seems that he is conflicted and feels responsible about the way his son turns out. In the mental institution, the son is actually the most misbehaved of all, and one underlying focus of the movie is on the sexual perversion of each of the characters.
