Anna Neagle and Michael Wilding star in this war drama directed by Herbert Wilcox. Diana (Neagle) is a WWII Wren on her way out to Singapore. During an air raid in Piccadilly, London, she meets Captain Alan Pearson (Wilding) and the pair quickly fall in love and marry. They enjoy a two-day honeymoon before Diana must depart for Singapore. When Alan receives news that the ship that was transporting the Wrens was torpedoed and that there were no survivors, he loses all hope of finding his wife and remarries. Diana, however, is not dead; she is marooned on an island with just a few sailors for company. How will Alan and his new wife react when Diana returns three years later?
