Michael Woodford was a company man. He'd risen through the ranks of giant Japanese firm Olympus to become CEO. But just weeks into the job in Tokyo he came across allegations of enormous fraud.

Yet his every attempt at investigation was blocked. Losing his job, facing a cover up and possible threats to his life, Woodford fled the country.

Then he did something Olympus didn't expect.

He fought back. Risking everything, Woodford went on the offensive. He exposed the crimes at the company's heart, brought down those who tried to silence him - and became a hero.
