Metropolis is a film about upper class citizens who own the city of Metropolis and lower class citizens who make it run by working at its machines. The plot of this film is that there is a ruler of Metropolis called Joh Fredersen who is a mean and ruthless man. He's son Freder is not like him, he is more caring then his father. These upper class type of citizens live in the upper level of Metropolis, where as the lower class citizens live underground in the level just above the machine rooms where they work.
Within the lower class there is a woman called Maria. Maria helps give hope to the lower class citizens by saying "between the mind that plans and the hands that build there must be a Mediator, and this must be the heart". Freder meets Maria and instantly falls for her. He follows her down into the machine level. The story goes on a bit with Freder trying to find her and seeing an accident happen within the workers. A piece of paper is found on one of the workers who was hurt and is taken to Joh. Joh gets annoyed that this has been bought to his attention by the head floor man and not his right hand man, so he fires his right hand man who then tries to kill himself, but Freder stops him.
There's a crazy scientist who loved Freder's mother before she died and he's been trying to find a way to get her back from the dead. He builds a robot that he will make to look like Freder's mother. As the story progress' on Joh finds out about Maria and dosent like the fact that the workers listen to her. Joh tries to destroy her by getting the scientist to make the robot to look like Maria. With the robot looking like her Joh thinks the scientist has given him control over the robot but really the robot is still listening to its maker. Later on in the story, Freder finds out that this Maria is not the real one and that she is trying to stir up a rebellion.
After the workers listen to the robot Maria and stop working at the machines, their home level is flooded and all their homes are destroyed. The workers soon realise what they have done and that she is evil, they burn her at the stake. This is where they see her turn from the Maria they see back to her robot form. At the end Maria tells Freder that he is the mediator, Jon is the mind and the works are the hands. Freder takes his father's hand and the hand off the head floor man and says they can work together.
