When 16-year-old Sally is evacuated to the English south coast, she is terrified by what lies ahead of her. All she knows are the sights and sounds of London's East End—but Sally swallows her tears as they leave the familiar landmarks behind, knowing that she has to be a grown-up girl and play mother to her six-year-old brother Ernie. Playing mother is nothing new for Sally—their real mother Florrie, a good-time girl, hasn't even come to the station to wave them off and Ernie, crippled at an early age by polio, is used to depending on his older sister. When they arrive in Cliffehaven, they're taken to live at the Beach View Boarding House where they're welcomed by the openhearted Reilly family headed up by warm, loving Peggy, and life begins to improve. Sally gets a job in a uniforms factory to help pay her way—and to pay for Ernie's expensive medicines—but then Florrie arrives in Cliffehaven, bringing disaster with her. And Sally is forced to work out where her true loyalties lie.
