On August 1, 2015, Mark Karpelès exits his luxurious home in Tokyo under police escort. Hiding his face under a cap he wears a carefully chosen t-shirt: "Effortless French". Hours later, Mark is indicted and imprisoned for forgery of computer data and embezzlement in connection with the disappearance in February 2014 of 850'000 Bitcoins, the equivalent of a half Million Dollars. Mark ran MTGox, the company responsible for this financial disaster and the biggest platform for virtual currency exchange, managing 80% of global transactions. He remains in pre-trial detention for the next year until the Japanese decides to release him, for lack of evidence. Mark is finally free to prove his innocence and this is his story.
