A nearby RAF bomber station sends some of its men to a staff dance at the factory, during which Celia meets and falls in love with an equally shy young Scottish flight sergeant Fred Blake (Gordon Jackson). Their relationship encounters a crisis when Fred refuses to tell Celia when he is sent out on his first mission, but soon afterwards they meet and make up, with Fred asking Celia to marry him. After the wedding they spend their honeymoon at the same south coast resort as the Crowsons went to in 1939, finding it much changed with minefields and barbed wire defending against the expected German invasion.
