Santa's good-hearted daughter, Kristen (Ireland), tries to save Christmas. Unlike her conniving older sibling Rudolfa, Kristen who embodies holiday cheer, is shocked to learn her father is fed up with the selfish mortal world and plans to retire from his duties. Unable to simply sit back and let Rudolfa take over the reins, Kristen cuts a deal with Santa. If she can convert a family on his naughty list - a single dad (John Dye) and his two bratty kids - by showing them the spirit of giving in time for Christmas, then Santa must continue to spread holiday cheer.
