She thought he had died. She made a new life. Then he came back...
Alice and Ben. A couple like any other. Bound together by love, work, children, familiarity, a shared sense of purpose.
Arguing about the usual things too - in-laws, whose career is more important, which of them is a soft touch with the children, who hates change and who craves it.
But when Ben takes a step into the unknown, and brings devastation on the family, it forces them to look at everything in a whole new way. Because, as far as they know, this is the end of the line for their family.
So what will happen if they get a second chance? Can they - should they - go back to the way they were?
