On a morning that seems just like any other, Robbie wakes in his bed, his wife Emily asleep beside him, as always. He rises and dresses, makes his coffee, feeds his dogs, just as he usually would. But then he leaves Emily a letter and does something that will break her heart. As the years go back all the way to 1962, Robbie's actions become clearer as we discover the story of a couple with a terrible secret - one they will do absolutely anything to protect.
