1844. From all sides, in a boiling Europe, the workers, the first victims of the "Industrial Revolution", sought to organize themselves before a frantic "capital" which devoured everything in its path. Karl Marx, a journalist and young 26-year-old philosopher who was the victim of the censorship of a repressive Germany, went into exile in Paris with his wife Jenny, where they were to make a decisive encounter: Friedrich Engels, the rebellious son of a wealthy German industrialist. Intelligent, bold and bold, these three young people decide that "philosophers have only interpreted the world, while the goal is to change it." Between challenging parties of chess, nights of intoxication and passionate debates, they feverishly write what will become the "bible" of workers' revolts in Europe: "The manifesto of the Communist Party", published in 1848, an unprecedented revolutionary work.
