When Sandra Cooper is offered the chance to move away from London with her children, it seems like a good opportunity to escape the 1940 blitz.
Her husband Harry is away in the army, and over the next five years she comes to experience the very worst that World War 2 can inflict on the people. As they settle into their new home, she realizes that the Hertfordshire town is not such a safe option after all.
Then along comes Edward; a young pilot who proves a good friend in unexpected circumstances. As Sandra becomes more and more fond of him, Germany prepares to launch their assault on London... and all of their lives will change forever.
