Flanagan's latest thriller for Netflix reimagines a 19th-century literary classic by transporting it to the 1980s and expanding its scope across nine episodes. The story centres on a young American arriving at an English country house to care for two orphaned siblings, where she encounters increasingly disturbing supernatural phenomena. This project represents another entry in Flanagan's expanding catalogue of dark, atmospheric adaptations that have found wide audiences on streaming platforms.

Rather than adhering strictly to the original, Flanagan uses it as a springboard to explore Gothic themes anew, drawing from multiple related works to expand the narrative and develop its ensemble cast. The series emphasises psychological complexity and romantic elements alongside supernatural horror, essentially framing itself as a love story within a Gothic setting. This approach distinguishes it from his previous similar project by centring community formed among strangers rather than examining a single family's internal bonds.
