Set on Christmas night, the film tells a story about Santa Claus's clumsy son Arthur Claus who discovers that the Santa's high-tech ship has failed to deliver one girl's present. In response, he goes on a mission to save her Christmas, accompanied only by his ageing grandfather, a rebellious yet enthusiastic young Christmas Elf obsessed with wrapping gifts for children, and a team of eight strong, magical yet untrained reindeer.
