As the clock strikes midnight, the family don their masquerade masks, but the true masks come off as inhibitions are shed. Jack Vegas, the patriarch, watches with satisfaction as his children and their spouses come together in a writhing mass of flesh. Aaliyah Love, Penny Barber, and Coco Lovelock, sisters by marriage, explore each other's bodies with eager hands, while their partners, Calvin Hardy, Tyler Cruise, and Joshua Lewis, join in, forming a tangled web of familial desire. Theodora Day, the youngest, watches with wide eyes before being drawn into the fray, her innocence lost in the throes of the orgy.
