Suffolk, 1939: Julia Compton has a beautifully well-ordered life. Once a promising musician, she now has a handsome husband who pays the bills, a young son she adores and a housekeeper who takes care of her comfortable home. Then on the eve of war something unexpected happens. She falls in love. The consequences are devastating. Cut off from family and friends, Julia loses everything. Penniless, denied access to her son, completely unequipped to fend for herself, she is cast adrift in wartime London with her bohemian filmmaker lover Dougie. As invasion looms and the bombs rain down her struggle is only beginning. While Dougie seeks truth wherever he can find it, Julia finds herself lost. Before long, ruined and broken, she faces a choice - succumb to her fate, or fight to forge a new identity in the heat of war.
