In a cozy, highly traditional suburb, the annual Christmas pageant is a rigid monument to predictability until the local terrors—the six neglected, unruly Herdman children—bully their way into the lead roles. Directed by Grace Bradley, a well-meaning mother thrust into the job after the regular coordinator is hospitalized, the production quickly descends into hilarious chaos as the Herdmans, who have never heard the Nativity story, interpret the biblical narrative through their own gritty, survivalist lens. What begins as a community's collective dread of a ruined tradition gradually shifts into a profound, heart-wrenching confrontation with the Gospel's true target: the broken, the outcast, and the forgotten. Through the Herdmans' raw and unvarnished reaction to the baby Jesus, the judgmental congregation is forced to look past their own polished moralism to rediscover the scandalous grace of the incarnation.
