Made in Germany during the Weimar Period, Metropolis is set in a futuristic urban dystopia and follows the attempts of Freder, the wealthy son of the city's master, and Maria, a saintly figure to the workers, to overcome the vast gulf separating the classes of their city, and bring the workers together with Joh Fredersen, the master of the city. The film's message is encompassed in the final inter-title: “The Mediator Between the Head and the Hands Must Be the Heart” 2).
