Barry Carter and his mates in Ridley Road are building a four-man giant skateboard. When Barry takes their creation for its first spin he is nearly run down by a young man with green spiky hair driving a VW Beetle.
This unknown man turns out to be the new tenant moving into the house at the end of the road. And so the mystery begins. His behaviour intrigues the four boys. He has a chair strapped to the roof of his car and startling flashes of light are seen coming from the house. Why is he so elusive? What are the strange shadows that drift across the windows at night? The children yearn to know the truth but nothing can prepare them for what they eventually discover and reveal.
