Confined to a wheelchair, his right leg encased in plaster after knee surgery, Lee has too much time on his hands, which he uses to watch the world go by through a pair of high-powered binoculars. He soon realises that all is not well in his neighbour's house opposite. In fact, he's quickly convinced that something despicable is going on.

Lee organises a family camping trip in an attempt to bring the generations together. But even though he has remembered to bring his guitar for campfire sing-songs, he's forgotten to check the weather. And when Lucy finds something in the woods that looks very much like a human bone, the unhappy campers cannot wait to leave.
