The #xxxxxxxxxxx room on an undisclosed Darknet network includes up to 18 of the world's best hackers. They all have three things in common: a great mastery of technology, an unusual past and absolute discretion. To hope one day to join the prestigious group of "La Tigresse", the co-opted candidates will have to perfect their knowledge and to demonstrate their abilities on a series of technical tests; a quest that can sometimes take years. In this ultra-compartmentalized network, the members participate in clandestine and spectacular actions that regularly make the front page of the specialized press. Some want to take revenge on the past, others want to make the world better; all became millionaires.
