Joe Marsh (Robert Arden) is a U.S. Army captain who goes on the run in Britain after committing murder. He breaks into a family's home and forces 7-year-old Tommy Martin (Richard Williams) to guide his escape through the surrounding rural territory. A bond begins to form between the child and the desperate fugitive, but Marsh's criminal nature cannot help but show itself again before the chase comes to an end.

Mather (Ryck Rydon), un meurtrier psychopathe en fuite, parle à un petit garçon très imaginatif, Tommy (joué par Richard Williams, 11 ans), en lui faisant croire que s'il le récupère tranquillement avec un fusil et de la nourriture, Mather lui donnera une introduction favorable au hors-la-loi Jesse James.
