Ninety-one-year-old Ira Levinson is in trouble. Struggling to stay conscious after a car crash, with his mind fading, an image of his adored - and long-dead - wife Ruth appears. Urging him to hang on, she lovingly recounts the joys and sorrows of their life together - how they met, the dark days of WWII and its unrelenting effect on their families. A few miles away, college student Sophia Danko's life is about to change. Recovering from a break-up, she meets the young, rugged Luke and is thrown into a world far removed from her privileged school life. Sophia sees a new and tantalising future for herself, but Luke is keeping a secret that could destroy it all. Ira and Ruth. Sophia and Luke. Two couples, separated by years and experience, whose lives are about to converge in the most unexpected - and shocking - of ways.
