Inspired by Kass Morgan’s novels, this series is set a century ahead, in a future where Earth has been deserted because of radioactive contamination. The remaining human population resides on a space station encircling the planet, known as the Ark. However, the Ark’s sustainability is limited. In a desperate measure, the authoritarian leadership selects 100 juvenile offenders, deemed disposable, to return to Earth and determine if it can once again support life.
