Love, mayhem, and confusion reigns supreme when Santa asks Jack Frost and Christmas Spirit "Krista" Claus to help with a problem.
Six-year-old Cecilia Monroe has written her Christmas wish letter with a magic pen, asking Santa to help prevent the hotel she and her mother live in and where her mother works from being sold. Santa has to bring in reinforcements to grant this Christmas wish.
However, Jack and Krista have their hands full. The man selling the hotel turns out to have an agenda beyond getting rid of the property to start a new life in California. Eric is making a final desperate act to get over his unrequited love for Tansy Monroe, Cecilia's mother.
The situation becomes more complicated when the seventy-three year old registration desk clerk is convinced hotel guests Jack and Krista are CIA agents!
