Last Tango in Halifax

Celia and Alan haven't seen one another for sixty years. When they're reunited via a website, their passionate feelings for one another are reignited. When Alan's car is stolen, he and Celia end up stranded and they call their respective daughters to pick them up. Apart from being in their mid-forties, it's obvious that arrogant Caroline and happy-go-lucky Gillian have almost nothing in common. Inside the cafe, Celia and Alan introduce them to one another and make a surprising announcement.

Celia and Alan buy an expensive new convertible and throw an engagement party at the farm while Caroline and Gillian apologize to one another for their behavior when they first met. William discovers his dad and Judith drunk together in the house when he comes home from school early one day. During the engagement party Raff is arrested by his Uncle Robbie for beating up Paul Jatri.

Celia and Alan decide on a civil ceremony at Southowram Hall, a creepy Medieval Hall near Halifax. A storm is brewing as they visit the hall, and as Alan tells Celia about a ghost in one of the bedrooms, the lights go out, and they find themselves locked in the ancient building. Meanwhile, after a supportive chat with Gillian, John tells Caroline he's moving back in whether she likes it or not.

Caroline and Gillian are worried about Alan and Celia, who appear to have vanished. In fact, they're locked inside Southowram Hall. A police search begins, with Robbie lending a hand. Cold and unable to sleep, Caroline and Gillian open up to one another and form a supportive bond.

Caroline throws herself whole-heartedly into her relationship with Kate and tells John that the 'someone' she's seeing is a woman. Devastated with the implications, he doesn't know who to turn to and ends up over at the farm, hoping for Gillian's sympathy. Alan and Celia have lunch in the pub with Harry and Maurice. Alan can't decide which of them should be his best man, so he ends up asking them both!

Celia reacts badly to John's revelation that Caroline is gay. When she and Alan have dinner with Caroline and Kate, she's very rude to Kate. Alan feels crushed after this, and tells Gillian that it's over between him and Celia. Back in Harrogate, a livid Caroline gives Celia an earful.
