The movie begins with an adult <a href="/actor/lauren-graham">Beth Bradley</a> reflecting on how the Herdman siblings—<a href="/actor/beatrice-schneider">Imogene</a> (played by <a href="/actor/beatrice-schneider">Beatrice Schneider</a>), <a href="/actor/mason-d-nelligan">Ralph</a> (Mason D. Nelligan), <a href="/actor/matthew-lamb">Claude</a> (Matthew Lamb), <a href="/actor/essek-moore">Ollie</a> (Essek Moore), <a href="/actor/ewan-wood">Leroy</a> (Ewan Wood), and <a href="/actor/kynlee-heiman">Gladys</a> (Kynlee Heiman)—are known as some of the worst kids in town. These troublemakers, whose mother remains unseen throughout the story, are infamous for causing chaos wherever they go. Their presence alone strikes fear into the hearts of both the children and adults in the town of Emmanuel.
Beth lives with her parents, Judy Greer as Grace, and dad <a href="/actor/pete-holmes">Bob</a>, along with her younger brother Charlie (Sebastian Billingsley-Rodriguez). The town is preparing for its 75th annual Christmas pageant, a beloved tradition, but disaster strikes when the usual director, Mrs. Armstrong, suffers an accident and breaks both legs. <a href="/actor/danielle-hoetmer">Mrs. Wendelken</a> (Danielle Hoetmer), a mother of Beth’s classmate Alice, attempts a critical remark about Grace's lack of involvement and volunteers herself to direct the pageant, much to Bob Bradley's dismay.
At school, Charlie faces teasing when Leroy steals his snacks repeatedly. When Charlie mentions that he gets plenty of treats at church, it sparks the Herdmans' first mysterious visit to the church, surprising everyone with their unannounced appearance. Rather than participating in traditional hymns or offering, the Herdmans pay close attention when Grace begins casting roles for the Nativity scene. Imogene boldly asserts she will be Mary, insisting that Ralph plays Joseph, with Leroy, Ollie, and Claude stepping in as the Three Wise Men, and Gladys volunteering as the Angel of the Lord. Despite Grace’s efforts to encourage the other children to volunteer, only the Herdmans seem eager, though Imogene threatens Alice to give up her Mary role.
During rehearsals, the Herdmans disrupt by pelting snowballs at the children until adults intervene. Inside, Grace recounts the Nativity story, which the Herdmans listen to intently—though with a rough-and-tumble attitude—especially when they express anger at King Herod's evil plans to kill Baby Jesus. Imogene and her siblings begin assigning roles, with Gladys even trying to scare others with a prop rod until Grace intervenes. Imogene's admiration for the image of Mary holding Jesus, which she deems "nice and pretty", leads Grace to encourage her to watch rather than participate, but Imogene insists on playing Mary.
As the story develops, Grace’s perception begins to shift. She starts to see how much the Herdmans' genuine interest in the story contrasts with their reputation. A pivotal moment occurs when Bob Bradley secretly helps the Herdmans—delivering Christmas ham to their impoverished home—a gesture that deepens Grace’s warmth towards them. The Herdmans, determined to learn more, grab a Bible and study the story of Jesus, laboriously preparing for the pageant despite skepticism from the town’s mothers. Meanwhile, Beth prays silently, hoping the Herdmans won't ruin the event.
Tensions grow as the community resists the Herdmans’ involvement. During a dress rehearsal, conflicts emerge over roles, with Imogene refusing to remove earrings that her sister Gladys pierced for her, and a minor fire starting after she is caught smoking a cigar. Critics and the other mothers grow more anxious, fearing the chaos the Herdmans might bring. Beth confronts Imogene, reminding her of how much her mother and the town have supported her siblings despite their reputation. Imogene confesses her doubts about being a “nice and pretty” Mary, but Beth encourages her to see the story through.
The night of the pageant arrives, and initially Alice steps in as Mary, but she quickly leaves the scene. The Herdmans then make their move, with Imogene and Ralph taking on the roles of Mary and Joseph—Imogene even removing her earrings. They add their own unique humor: Imogene's playful burp as Baby Jesus (a doll), and Claude, Ollie, and Leroy bringing ham as their gift instead of frankincense or myrrh, symbolizing their affection for food. Gladys commands the scene with shrill authority, earning laughs from the audience. As the play concludes, Imogene begins to tear up, moved by the genuine Christmas spirit she’s just experienced for the first time. The praised performance ends with applause, and for the first time, the townspeople warmly accept the Herdmans.
Beth concludes her story by telling the children about what became of the Herdman siblings. <a href="/actor/esek-moore">Ollie</a> turned into a veterinarian specializing in cats; <a href="/actor/matthew-lamb">Claude</a> is now a respected school teacher; <a href="/actor/ewan-wood">Leroy</a> had some run-ins with the law but is now doing better; <a href="/actor/kynlee-heiman">Gladys</a> became a flight attendant whose passengers always listen; <a href="/actor/mason-d-nelligan">Ralph</a> is now the pastor of a large church in the Midwest; and <a href="/actor/beatrice-schneider">Imogene</a> pursued acting briefly before becoming a director of a Christmas pageant at Ralph's church. She now is a mother of five and remains actively involved in her children’s lives, contrary to her own mother’s neglect.
This story highlights how the stuck-up tradition and the community’s preconceived notions can be challenged and transformed through honest connection and understanding. Beth's final reflection emphasizes that the true meaning of Christmas is about sharing joy and kindness, regardless of reputation or appearance. The movie ends with a warm, heartfelt reminder of the importance of compassion, family, and the enduring spirit of the holiday season.
