Sam and Tusker, romantic partners for 20 years and
amateur astronomers, undertake a road trip in a
campervan across
England to the
Lake District, to visit some of their favourite spots and for a reunion with friends and family. Tusker has been diagnosed with
early onset dementia, with his progressing illness putting a strain on their relationship. He is in the middle of writing a book, but is struggling with it, refusing to show it to Sam. Sam is a pianist/composer preparing for what he says will be his final
piano concert. On the way they have a scare when, as Sam is buying a few things for them to eat in a shop, Tusker takes their dog for a walk without his mobile. He gets disoriented, but luckily Sam manages to find them. Shaken up by the experience, Sam tries to hide from Tusker how much it affected him. As they go, they continually banter and gently bicker. The couple spend their second night on the edge of a lake they had visited together 20 years ago, in the early days of their relationship. The pair arrive at Sam’s sister Lily’s house, where they are put up in his old room. She again suggests Sam at least look into a carer to help take some of the burden off, but he insists it's not yet necessary. Later, on a walk through the woods, Sam tries to talk with Tusker about near-future adjustments they'll need to make on their home and his intention to stop performing, but he refuses to hear about it. The rest of their family and friends later gather for a party in their honour, a surprise to Sam. During subsequent conversation with one of their friends, Sam finds out Tusker has been having difficulties writing, something he's kept from him. Sam heads into their camper van and discovers in his journal that Tusker’s writing has been declining steadily over time. He also discovers that Tusker has a vial of
pentobarbital and has made a farewell audio tape, explaining that he intends to take his own life. Sam says nothing. The pair head to a leased cottage in the countryside. Sam confronts Tusker about his discovery and plays the tape to him, revealing Tusker’s plans to die by
suicide before his dementia becomes too severe. Sam strongly and pleadingly argues with him against this idea, to no avail. They make up the next day and have an intimate night together. The next morning, as Sam plays the piano, he lets Tusker know that he accepts his decision and wants to be at his side when it happens. In the final scene, Sam appears on stage, playing the beautiful piano piece that Tusker loved so much. ==Cast==
