Last Tango in Halifax
This romantic comedy involves Alan Buttershaw and Celia Dawson, two 70-something widowed people. After their respective grandsons put their profiles on a popular social-networking site, the two rediscover feelings for each other similar to the ones they had many decades earlier as teenagers. Their relationship is a celebration of the power of love at any age, but it comes with obstacles -- namely their families. Alan's daughter, Gillian, and Celia's daughter, Caroline, are polar opposites and, while neither would ever think about getting in the way of her parent's happiness, the situation is a bit disconcerting.
