My name is Joe Claus, aka the new Santa Claus. On the eve I am to take over for my dad, my dear sister decides she's going to do a disappearing act.

Blamed for her leaving, I am sent to down to Florida of all places. It's hot, I'm pissed, and my Christmas spirit is quickly fading. Until my eyes fall on Crystal Sugarplum, the baking sweetheart who thinks Christmas is a conspiracy from the sales companies.

Can I be the Undercover Santa I was sent to be? Or will I end up on the naughty list for wanting to spank one delectable non-believer? Either way this holiday season, Santa's getting his hands on his own Christmas Gift.
