Childhood sweethearts, Alan and Celia are both now widowed and in their 70s. When their grandsons connect them through the internet, they rediscover feelings for one another that just might have blossomed 60 years ago. Still, it's never too late... or is it? For all the what-might-have-beens, their lives have moved on and both Alan and Celia have daughters, whose dysfunctional lives bring drama at every turn. Celia's daughter Caroline, a career-focused head teacher, is dealing with the return of her adulterous husband John; while Alan's hard-working farmer daughter Gillian is distracted by the advances of a younger lover and the accusations of her brother-inlaw, who's convinced she was involved in the death of her husband. Neither daughter would ever dream of getting in the way of their parents' happiness. But somehow life and love are never quite that straightforward.
