Socially awkward misfit AJ has a few things on her mind. Mostly how the methane from all the cows is destroying the planet, and how she’d rather be anywhere else than on holiday with her family. Mum Tina drags AJ to a holiday park in Dorset, alongside neurotic and heavily pregnant older sister Lucy, curious younger sister Dayna and Lucy’s foot-rubbing boyfriend Steve. To make matters worse, there’s no Wi-Fi. AJ is determined to have the worst week of her life, until she becomes captivated by carefree lifeguard Isla. SWEETHEART is a coming of age tale for a new generation.
