Shy, timid and fresh out of high school, London boy Hero is dragged uncomfortable and awkward along to a music festival by his older brother. His path collides with Josephine who doesn't seem to know what she wants out of life so instead spends her time living it up and avoiding her responsibilities. One summer night changes their lives and over the course of the months that follow they simply become...different. But was it a mistake or was it fate at work?
