Journalism student Gabe Martin gets his first professional assignment—to write about a Christmas charity dinner that benefits a children's home. It sounds like a total snooze-fest until Gabe learns that the event's Santa is a mystery man. He shows up in costume and no one has a clue who he is. Uncovering Santa's identity sounds like the perfect angle to turn a fluff piece into serious journalism.

Mack "The Mountain" McDonall, at 6'10", is University of Wisconsin-Madison's enormous star wrestler. When Gabe first claps eyes on him at a wrestling match, it's lust at first sight. Gabe's friend, Jordan, sets up the pair on a date. But when Gabe chatters on about his plans for outing Santa, Mack goes cold, and their first meeting becomes an epic fail.

As Gabe researches the children's home, he learns that Mack has secrets a guy famous for being a brute wouldn't want the world to know. Can Gabe find his holiday spirit, write a killer article, win the heart of a surly giant, and give everyone a very merry Christmas?
