Between censorship and police raids, riots and political upheavals, Karl Marx and Friedrich Engels meet in Paris in 1844, and together, become defining voices for the burgeoning labour movement. Expect fiery exchanges of ideas over drunken bonding sessions, nurturing support from their adoring partners and masses of righteous indignation at the social inequalities magnified by the industrial revolution. 
 
This humanising period drama tracks the lives of these radical young philosophers from their first meeting through to writing The Communist Manifesto, and the flying sparks that helped ignite and inspire the most significant theoretical and political transformation of the world since the Renaissance.
