Anora (Mikey Madison), a sex worker from Brooklyn, gets her chance at a Cinderella story when she meets Ivan (Mark Eydelshteyn), the teenage son of a Russian oligarch. Taken with her, Ivan takes Anora to Las Vegas on a trip with his friends. On a whim, the two are married in Vegas.

Now living in the mansion Ivan's parents rented for him in New York, Anora enjoys the fine life, but once the news of their marriage reaches Russia, her fairytale is threatened as his parents set out for New York to get the marriage annulled.
