The Beast Within (1995)

Through the adults surrounding him, eight year-old Frederik is confronted with animalistic desires, abandonment, death, hatred, and envy. His parents hold little love for each other, and his mother starts an affair with Frederik's teacher. When Frederik's father is killed, the little boy opts to shut out the world, and deal only through his alter ego, The Beast Within, who perceives everything through a haze of despair.
