Sima and her family are pressed to the rough, cold ground among 50 others. They lie next to the tall fence designed to keep them in. The wires are cut one by one.
When they make their escape, a guard raises the alarm. Shouting, smoke bombs, people tackled to the ground. In the chaos Sima loses her parents.
Dad told her to run, so she does, hiding in a school and triggering a lockdown. A boy, Dan, finds her hiding in the toilet block.
What should he do? Help her? Dob her in? She's breaking the law, but is it right to lock kids up? And if he helps, should Sima trust him? Or run?
This moment, these decisions, will change the course of their lives.
