Imogen Brown is a normal 16 year old girl. She´s obsessed with beach volleyball, she occasionally enjoys the company of her younger sister Jemima, she´s saving for her first car ... and she feels like she doesn´t belong. She thinks that her parents, Kat and Dylan are hypocrites, playing the perfect family when she knows they really argue all the time. What Imogen doesn´t know is that they´re in financial difficulty, after Dylan lost a number of his construction clients. Kat is trying to work things out with him, as all she´s ever wanted is a tight-knit family - the family she never had.
One Friday evening, Kat and Dylan have their biggest fight yet - Dylan is snappy and out of character, saying things he doesn´t mean. When Kat goes to wake Imogen the next day, she´s not in her bed. Kat and Dylan call her friends, but no-one has seen her since the previous day at school. Jemima had stayed at a friend´s house, and hadn´t seen or heard from her sister since the previous morning. Imogen has gone missing.
