Sweetbitter follows 22-year-old Tess (Purnell) who, shortly after arriving in New York City, lands a job at a celebrated downtown restaurant. Swiftly introduced to the world of drugs, alcohol, love, lust, dive bars, and fine dining, she learns to navigate the chaotically alluring, yet punishing life she has stumbled upon. This is the story of a young woman’s coming-of-age, set against the rich and grimy backdrop of exclusive restaurants, conjuring a nonstop and high-adrenaline world evoking the possibility, beauty, and fragility of being young and adrift.

“Ella’s portfolio of work and the array of her characters and performances in her young career are truly remarkable. We are excited for fans of the book and audiences to meet Tess,” said Starz President of Programming Carmi Zlotnik. “We are also excited by Richard’s vision to bring the book’s richly written sensory experiences from the page to the screen.”

Sweetbitter is Purnell’s first major television role. Her film work includes the role of Emma in Miss Peregrine’s Home for Peculiar Children. Other credits include Never Let Me Go, Kick-Ass 2 and Maleficent.
