What is the main story of modern times?

1928 ~ 1934 is the transition period of American movies. At this time, American industrial production is facing a crisis, and the intensification of domestic class contradictions has triggered a serious political crisis and economic crisis. At this time, Chaplin wrote, directed and performed Modern Times.

Modern Charlie, dressed in overalls, stood by a long rotating conveyor belt. His movements are mechanical and simple, holding a wrench and tightening the screws of the parts from the belt. Parts spread quickly and the next worker hit them with a hammer. The conveyor belt does not give workers a second of freedom, even if they go to the toilet, they have to wait for the foreman to replace them. They can't even squat down to the toilet, and the rude voice of the boss's foreman is also forced. The monotonous mechanized labor finally made Charlie nervous, and he made a series of jokes.

Modern Times reveals the essence of American society by analyzing people's unique destiny through concrete images. This is an unprecedented creation in American film history. Chaplin raised realistic pictures to the height of philosophy.
