Joker

Arthur Fleck is a professional clown and aspiring stand-up comedian who lives with his mother, Penny, in crime-ridden Gotham City during the early 1980s recession. He suffers from a neurological disorder that causes him to have random, uncontrollable laughing fits, requiring medication for which he depends on social services to obtain. After Arthur is attacked by street urchins, his co-worker Randall gives him a revolver for self-defense. Arthur pursues a relationship with his neighbor, single mother Sophie, and invites her to see his routine at a comedy club.
