Leena is too young to feel stuck. Eileen is too old to start over. It's time for The Switch... After blowing a big presentation at work, Leena takes a two-month sabbatical and escapes to her grandmother Eileen's house for some overdue rest. Eileen is newly single and about to turn eighty. She'd like a second chance at love, but her tiny Yorkshire village doesn't offer many eligible gentlemen . . . A life swap seems the perfect solution. But with a rabble of unruly OAPs to contend with, as well as the distractingly handsome local schoolteacher, Leena learns that switching lives isn't straightforward. In London, Eileen is a huge hit with her new neighbours, and with the online dating scene. But is her perfect match nearer to home than she first thought?
