One of the most iconic sitcom characters of all time returns for an animated movie musical event. The holiday season has arrived, and brilliant but accident-prone Steve Urkel has already ruined his local celebration by publicly humiliating a shopping mall Santa. In his attempt to make things right and score some nice points with the big guy in the North Pole, Steve creates an invention that only makes things worse. Using his big brain and even bigger heart, Steve must find the real Santa to see if together they can help the city rediscover the holiday spirit.
