On Christmas Eve, the Reynolds family gathers in their cozy country home for the first time in years. The atmosphere is thick with excitement and laughter, but also with old grudges that resonate among family members. The patriarch, Tom, a somewhat bitter widower, tries to maintain peace while his four children, each with their own insecurities and aspirations, struggle to find a sense of belonging.
Melissa, the eldest, returns from Los Angeles after her failed acting career and feels more lost than ever. Jake, the middle child, has just gone through a breakup, and his pessimistic attitude doesn't help improve the festive mood. Melissa’s rebellious twin, Chloe, is obsessed with documenting the reunion for a viral vlog, leading to many comedic and tense situations. Meanwhile, the youngest sibling, Oliver, struggles to break out of his geek shell and find his voice in the world.
As the night progresses, secrets come to light, and family members are forced to confront their differences. With the help of an unexpected holiday spirit, they will learn that the true magic of Christmas lies not in the gifts, but in the acceptance, forgiveness, and love that still binds the family together. Amid all the misunderstandings, the Reynolds discover that sometimes the path to happiness can be a journey filled with laughter and tears.
