Double Booked follows a successful self-help writer (Scott) and his heavily pregnant wife (Zazie Beetz) who organize a weekend away at a secluded lodge, only to encounter another couple (Sterling K. Brown and Alexandra Daddario) at their cabin when they arrive. With a blizzard moving in they are forced to spend the night together, and what seems like an innocent system error turns into a chilling battle of deceit with deadly consequences.
