When journalist Cheng Lei was detained by Chinese state security agents, she thought would be freed within the week. Instead, she was held on absurd espionage charges for more than three years, much of that time spent in isolation.

When Cheng Lei moved back to the country of her birth after the dramatic opening up of China to the world, she was a part of something exciting and historic.

That all changed after Xi Jinping came to power, and Australia's relations with China deteriorated.

In this first episode of a two-part series, Lei explains how eventually, she found herself detained on bogus espionage charges, and held for more than three years in a Chinese detention centre.

For the first six months of her detention, Lei was isolated and alone except for the rotating female guards who stood over her 24 hours a day.

Lei was not allowed to speak to these guards, she was forced to sit on the edge of her bed for 14 hours a day, she had to ask permission to do anything, she was not allowed to close her eyes and intermittently she was taken to a room, tied down in a chair and interrogated about allegedly sharing state secrets with foreigners.

Lei learned how to ration books, she practised German vocabulary, wrote scripts in her head and thought of her two children to stay sane under torturous conditions.
