In this heartwarming and uplifting drama, childhood sweethearts Alan (Derek Jacobi, "Gladiator", "The King's Speech") and Celia (Anne Reid, "Coronation Street", "Upstairs Downstairs"), both widowed and in their 70s, fall for each other all over again when they are reunited on the internet after nearly 60 years. Their relationship is a celebratory tale of the power of love at any age. But this is also a story about family, and with family comes baggage. Celia's respectable, head teacher daughter Caroline (Sarah Lancashire, "Lark Rise to Candleford", "Upstairs Downstairs") is juggling bringing up two boys and dealing with her husband's infidelity, while Alan's rebellious, complicated middle-aged daughter Gillian (Nicola Walker, "MI-5", "Inside Men") struggles to make a living on a beautiful but bleak farm. How will these two very different women cope with their parents' announcement that they've decided to get married.
