Dan Hodges is devastated when his wife Nora dies during the early days of the war. Working long hours in a Portsmouth shipyard, how is he to look after his two sons, Gordon and Sammy? Then Gordon, something of a tearaway, is sent to an approved school, which leaves young Sammy alone in the house until neighbours in April Grove intervene and Sammy is evacuated to Bridge End, a village near Southampton. Ruth Purslow, a young childless widow, takes him in, her compassion aroused by his plight. Slowly, as they grow closer, Ruth begins to dread the time when Sammy must return to Portsmouth . . .
