On Christmas Eve, Greg, a lonely, taciturn policeman, has no qualms about abandoning his daughter to go on a mission. To teach him a lesson, Santa decides to grant his daughter's wish: that her father resemble Richard Silestone, the good-natured, debt-ridden family man from the Christmas movie she loves. As Greg is sent to this unlikely world, Richard mistakenly lands in the real one. Upon awakening, both men realize they have no choice but to succeed in each other's mission to regain their respective lives: dismantling a dangerous drug ring for Richard and saving the family home for Greg by winning the local figure skating competition.
