Alice Lake has arrived in London from Liverpool to start her training as a district nurse, but her journey has been far from easy. Her parents think that she should settle down and get married, but she has already had her heart broken once and isn't about to make the same mistake again. Alice and her best friend Edith are based in the East End, but before they've even got their smart new uniforms on, war breaks out and Hitler's bombs are raining down on London. Alice must learn to keep calm and carry on as she tends to London's sick and injured, all the time facing her own heartache and misfortune while keeping up the spirit of the Blitz.
