It’s a significant evening for the Buoitton Family. Charles and Linda, a fabulously affluent couple, host an intimate dinner for their nearest friends and relatives. As the meal is about to begin, Charles raises his glass to toast the family but collapses face-first onto his plate, dead. Linda admits to poisoning him and reveals she has also poisoned everyone present, all in a bid to claim the fortune. The guests are faced with a dire ultimatum: they must choose one person among them to kill and take responsibility for both deaths to receive the antidote, or they will all perish within an hour. What ensues is a frantic and chaotic exchange among the highly stressed group members, who, in their desperate bid to decide who should die and who should be the murderer, unearth long-buried secrets they’ve kept from each other for years.
