For Cheng Lei, being stuck in a Chinese jail was like being buried alive in a concrete coffin. Wrongly incarcerated on espionage charges, the Australian journalist endured years of hell. Her hair fell out, she suffered insomnia and was only known by a number. But the worst part was not seeing her two young children. Almost two years after she was released and reunited with her family, Lei joins Gary Jubelin to share what it took to survive.
