All the Little Animals (1999)

Story about a young guy who sees with the eyes of an animal. Bobby is a brain-damaged adolescent who takes to the woods, finding wonder and a home in the natural world. But there is danger also in nature and beneath the surface there is something disquieting going on. When Bobby meets Summers, an old man who is also in some ways cut off from society, they develop an uneasy rapport, united at least in fear of Bobby's step-father De Winter.
