When a doubting young boy takes an extraordinary train ride to the North Pole, he embarks on a journey of self-discovery that shows him that the wonder of life never fades for those who believe.

Arthur Christmas reveals the incredible, never-before seen answer to every child's question: how does Santa deliver all those presents in one night? The answer: Santa's exhilarating, ultra-high-tech operation hidden beneath the North Pole. But at the center of the film is a story about a family in a state of comic dysfunction and an unlikely hero, Arthur, with an urgent mission that must be completed before Christmas morning dawns.
