Ever since the Traditional Party came to power, everything that 15-year-old Ruby took for granted -- hanging out with her boyfriend Luke, voicing her opinion and wearing what she wants -- has been taken away. And things are getting worse. Soon Ruby and her family find themselves taken to a prison camp far from home. Each person is allocated a number -- Ruby is number 276. Forced into hard labour and with friends and family going missing every day, Ruby knows she has to escape and let the world know what is happening. She has to somehow cling on to her identity and fight back. Her life depends on it.
