Carter Oosterhouse and Taniya Nayak judge elaborate Christmas displays created by families across the country. Each episode features the holiday home transformations of four families that were selected through a nationwide search based on past elaborate Christmas light displays, choreography, and extravagant designs as they compete to deck their homes out in the ultimate show of Christmas spirit. Once a winner is chosen, the judges return to the home to congratulate the family and present the $50,000 prize.
