Dimitri, a young reporter, investigates the origins of the Internet; contrary to popular belief, the data transmission system that is the basis of the digital revolution was developed by the French engineer Louis Pouzin. The latter, having undergone significant pressure from French authorities in 1974, had to put an end to his research; as a result, his invention was recovered by the Americans. Dimitri's investigations quickly lead him to a powerful industrialist, whose brilliant and sarcastic portrayal of himself exposes the existence of a "certain France" and the power of the lobbies.
