26 year old Karl Marx embarks with his wifeJenny, to the road to exile. Back in 1844 at Paris, he meets with an industrialist's son, Friedrich Engels, who is exploring the sordid arrival of the working class. Engels supplies the new vision of the world of the young Karl Marx with the final piece of this puzzle. Together, between riots and the repression of the police, censorship and political upheavals, the labor movement will be led by them during its development to a modern era.
