Josh, an adopted child, finds family life somewhat lacking and attempts to find solace in books and his hideaway treehouse. His brother bullies him and finally, when he can't stand it any longer, he commits the ultimate revenge!

The Josh Shelter is a film about sibling rivalry, an experience we've all had unless we were an only child. The film also deals with adoption and the problems which arise when there are both a natural and adopted child in the one family. The issues of this film are those with which children can particularly empathise.
