At Chicago's O'Hare, Ira longs for a real Christmas snow. He meets Mikey Amato in a busy airport play area, and the two hatch a plan to swap places. Their exchange seems risky, but they cling to the belief that the holiday spirit can bridge their worlds.

They trade hats, coats, ID tags, and even Ira's glasses in hopes of passing as one another. They share phone numbers and swap a postcard with Mikey's cousins’ details, creating a loose safety net. The disguise is imperfect because Ira's eye prescription could give him away, but they persevere.

Ira lands at Seattle–Tacoma International Airport and is greeted by Libby and Walt Wilson and their kids, while Mikey arrives in Florida to meet Ira's grandparents. The two families move toward Christmastown, Washington, unaware of the swap's full consequences. The stage is set for a shared adventure that will test their bonds.

In Christmastown, Ira experiences a town buzzing with holiday music and talent. He becomes determined to stage a community performance called Christmas Is For Everyone. The idea of a collaborative, inclusive show begins to take shape.

Jessica and Spike busk on the streets to fundraise and draw attention to the show. Clare writes a song for the performance and helps recruit local kids to audition. A chorus forms around Ira's central message of inclusivity and shared joy.

The town's bully unleashes his dog, Killer, on Ira, causing him to climb a tree in fear. Clare and Ira rescue Killer, turning the frightening moment into a turning point for their new community. The incident helps unite the town through a shared goal.

Killer becomes part of the show, and the production is rebranded as Mistletoe to reflect the community's healing. The dog's presence helps soften tensions and invites residents from both sides to collaborate. The town discovers the power of inclusion and teamwork.

Back home, Mikey suffers a broken arm as holiday plans advance. Ira's parents rush to support him, and the truth about the place swap starts to surface. Rather than condemning one another, the families decide to confront the situation together.

The two families choose unity over conflict and prepare for a shared celebration. Ira's family travels to Washington to surprise Mikey on the night of the big performance. The moment underscores the story's message that family and forgiveness can bridge cultural divides.

Mikey's Florida relatives react with astonishment and pride when they learn the full story. They realize the swap helped bring the families together and support their beloved kids' newfound connection. The revelation strengthens the holiday's message of unity.

The community gathers for the big performance and sings 'Christmas Is For Everyone' as a unifying anthem. Ira's improvisation and the collective spirit win praise from both families. The audience joins in, sealing the film's message of resilience and inclusion.
