Arthur Fleck is a struggling clown and part-time comedian living in the crumbling streets of Gotham City. Ignored by society, mocked by his peers, and surviving on a diet of whatever he can find in the back of the fridge, Arthur's grip on reality begins to slip. As the city's inequality grows and the rich feast while the poor go hungry, one bad day pushes him over the edge. What emerges is not just a villain, but a symbol for everyone who's been told they've had enough.
