After accidentally setting fire to his foster parents’ house, Robbie, a six-year-old boy, runs away. He searches for a hiding place and runs into a warehouse. Clattering down the steps, he accidently runs into the arms of a man, Chris Lloyd (Dirk Bogarde). Robbie sees a body lying nearby. Thinking that the boy will give him away to the police, Lloyd takes the boy with him and heads to the Scottish border. The more time they spend together, the closer they become, so when Robbie falls seriously ill, Lloyd has to make a difficult decision.
