It’s the most chaotic sequence in “Anora.” It’s also the turning point of the movie.

Brooklyn escort Ani (Mikey Madison) basks in the glow of newlywed bliss after impulsively marrying Ivan (Mark Eydelshteyn), the son of Russian oligarchs, at a hole-in-the-wall Vegas chapel. The ink has barely dried on the marriage certificate before the fantasy of her fairytale romance is shattered. Two hired henchmen, Igor (Yura Borisov) and Garnick (Vache Tovmasyan), barrel through the doors of the glass-enclosed mansion Ani and Ivan have burrowed themselves in. Word has gotten to Ivan’s powerful parents about their marriage — ill-advised and a sham, they argue — and a speedy annulment is the only solution.

What transpires is a frenetic 30-minute scene that plays out in real time. It reaches a crescendo once Toros (Karren Karagulian), a paid fixer on Ivan’s parents’ payroll, arrives at the mansion to bully Ani into kowtowing to their demands.
