Lou Channer wants a life outside of North Devon, somewhere she's never left. She yearns to contribute to the war effort and takes a job as a clerk in the Royal Canadian Naval Yard in Plymouth, lodging with other girls from the depot who take her under their wing. When Lou catches the eye of local wheeler-dealer Harry, who dazzles her with nights about town, she finally feels like one of the girls. And when Lieutenant Douglas Ross asks her out, Lou can't decide who to give her heart to. But during war, tragedy is always just around the corner, and when Lou's depot is burgled, she's suddenly the primary suspect – and her whole future is on the line.
