Perennially bored and just slightly rebellious teen AJ (Nell Barlow) finds herself forced to go on holiday to a caravan park in Dorset with her mum Tina (Jo Hartley), younger sister Danya (Tabitha Byron), older sister Lucy (Sophie Di Martino) and her partner Steve (Samuel Anderson). She’s not happy and attempts to hide away from the world – behind her sunglasses, beneath her hat and within the pages of a book. But then she sees lifeguard Isla (Ella-Rae Smith) and everything changes. Well, sort of. There’s Tina’s homophobia. And although Isla seems keen, how the hell is AJ going to deal with all the boys that hang around the pool try to curry favour with her?
