For the past eight years, Scott Calvin has tirelessly worked as Santa Claus and likes it now. However, this does not mean that he does not have any worries. On the approaches to the next New Year, the hero suddenly discovers that his son Charlie is a bully, and he immediately has to find a Mrs. Claus under contract conditions, because a bachelor Santa is a violation of all conceivable rules. In addition, while trying to solve the problems, he inadvertently instructs his duties to a counterpart, who in his absence turns life at the North Pole into a total chaos!
