Inspired by the film "Fight Club" and free-fight, whose competitions are banned in France, clandestine fights are all the rage in the cities. These clashes where all blows are allowed are the joy of punters who invest thousands of euros. In the United States, traders and golden boys compete at parties organized in upscale nightclubs. These meetings, of rare violence, serve as an outlet for their stress. Investigation also in Thailand where young French people learn to fight in boxing factories.
