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.
