Alexander Sterling holds his engagement party at a Manhattan hotel. His powerful mother Eleanor cancels lucrative European business deals and flies home, bringing a Hamptons estate deed and an invaluable sapphire as gifts for his fiancée Chloe. Bridesmaid Jessica takes photos of the affectionate mother son pair, leading Chloe to mistake Eleanor for Alexander’s sugar baby. Along with Jessica and other bridesmaids, Chloe assaults, illegally detains and humiliates Eleanor. They destroy the precious gifts and Eleanor’s only photo of her late husband, then move the badly injured unconscious Eleanor to a side lounge. Alexander arrives at the banquet unaware of the attack. Strange guest comments and torn fragments make him sense something wrong. He hurries to the side lounge and finds his wounded mother, then returns to the ballroom in rage to hold everyone accountable. Desperate, Chloe fakes pregnancy to grab Sterling wealth. Surveillance, audio and witnesses expose her infidelity and inheritance murder plot. Chloe, her accomplices and the Davis family face bankruptcy and criminal charges. The engagement is called off, and mother and son share a quiet dinner on this chaotic Thanksgiving night.
