Margot (Anya Taylor-Joy) and Tyler (Nicholas Hoult) visit Hawthorn, an exclusive restaurant on a coastal island boasting an extravagant tasting menu. Led by acclaimed chef Julian Slowik (Ralph Fiennes), the restaurant only accepts an elite selection of guests, including corporate leaders, movie stars, and wealthy couples. As the guests consume one course after the other, they soon find out they're part of a bigger, more ominous culinary plan.
