Bribed with 500 euros, seventeen-year-old Caylin agrees to go with her parents on a package holiday to Tuscany. She soon regrets her decision, leaves Mum and Dad behind at the hotel and hitchhikes alone to the city of Siena in search of something more exciting.
But Caylin's big adventure in Siena soon gets scary and dangerous when she meets a girl, Lula, who brands her a thief, which leads to Caylin being ostracised by her new best friend, Stefania. Meanwhile, unknown to Caylin, twenty-one-year-old Joe has volunteered to leave the holiday group to search for her and make sure she's safe, or at least that's his story anyway! Caylin makes two dramatic discoveries, one about Joe and the other about Lula. Caylin's adventure starts to spiral out of control, until love intervenes to give her the chance of a new life.
