When Billie's two crushes show up at the cuddle cabin, she enlists Justin in a game of keep-away that ends with a broken heart. Meanwhile, Maisy plans a celebrity soirée for cottagers to remind them why they need a Boathouse.
Justin returns from living abroad after a break-up with his long-term partner, in the hope of reconnecting with the biological daughter that he gave up for adoption in his teens. His plans to create new memories with his city-loving daughter Billie at the idyllic lake from his childhood go awry when he finds out his father left the family cottage to his 'picture-perfect' stepsister, Maisy-May.
