After the success of Yellowjackets, Ella Purnell went on to lead arguably the greatest live-action video game adaptation so far, Prime Video's Fallout. Season 1 premiered in 2024, and Season 2 came shortly after in December 2025. But, between adventures in the post-apocalyptic landscape of former America, Ella Purnell returned to UK shores for a criminally underrated serial killer thriller. Season 2 of her killer thriller is in the works and now is the perfect time to catch up on Season 1.
