　　The film centers on the Herdman kids, who are the absolute worst. They lie, they steal, they bully… and they’ve hijacked the town Christmas pageant. As the rowdy and raucous siblings force themselves into all of the lead roles, they drive the pageant’s director, Grace (Judy Greer), and other members of her family, including husband Bob (Holmes), up the wall. But through their misfit mischief, these unlikely messengers might turn out to be the ones to deliver the town’s sensational and moving portrayal of the true meaning of Christmas.

　　Driving home late at night during a heavy rainstorm, Glen experiences car trouble. Near where his car gets stuck, he spots a house, knocks on the door and is greeted by an oddly friendly middle-aged man, Arthur, and his younger wife, Cyndi. The strange couple pours him a drink, and then more drinks, followed by an unexpected offer that Glen can’t refuse. Elsewhere, a young woman, Katie, is feeling emotionally weighed down by a secret romantic arrangement that feels like a textbook case of gaslighting. And at the same time, in a nondescript research facility, medical professional Julie begins questioning her role in a bizarre experiment, fearing that she’s doing more harm than good.
