After a spectacularly messy breakup with the Joker, Margot Robbie’s Harley Quinn is determined to carve out her own path in Gotham City, only to discover that her newly single status has made her a target for every criminal she’s ever wronged. Declaring her independence with explosive flair, Harley soon finds herself at the center of a chaotic manhunt when a young pickpocket named Cassandra Cain (Ella Jay Basco) steals a priceless diamond belonging to the sadistic crime lord Roman Sionis, played with delicious menace by Ewan McGregor. Forced into an uneasy alliance with a trio of unlikely heroes—the vigilante Huntress (Mary Elizabeth Winstead), the sharp-shooting detective Renee Montoya (Rosie Perez), and the soulful singer Black Canary (Jurnee Smollett)—Harley must navigate a city full of double-crosses, glitter bombs, and hyper-violent mayhem. Directed by Cathy Yan, this R-rated superhero comedy blends kinetic action with a vibrant, punk-rock aesthetic, delivering a story of messy friendship, female empowerment, and one woman’s fantabulous journey to finally stand on her own two feet.
