It's 1948 and Sister Beatrice, who runs the St Saviour's Children's Home, knows that many children are still looking for a safe haven. One such arrival is Mary Ellen whose mother is gravely ill. The one silver lining is her best friend, the tearaway Billy Baggins. When an unwelcome face from Billy's past arrives on the scene, things are brought to a head. Can the women work together to keep Billy on the straight and narrow?
