Benjamin Armstrong (MORRIS CHESTNUT) is an aspiring songwriter who writes love songs but has yet to find true romance for himself. To pay the bills, he works as a department store Santa, along with his friend Jamal (FAIZON LOVE) who plays his adult-sized, elf assistant. One day, young Emily Taylor (KHAIL BYRANT) sits on Santa's lap and rather than ask for toys for herself, she asks for a nice man to meet her divorced and harried mom, Nancy (GABRIELLE UNION).
Since she's an attractive woman and he's single, Benjamin figures he could be that nice guy. Nancy's friends, Robin (JILL MARIE JONES) and Brenda (RACHEL TRUE), certainly think he's quite the catch, but she has her hands full. That's not only from doing her best to raise Emily and her brothers, Mikey (JEREMY GUMBS) and John-John (MALIK HAMMOND), but also dealing with their deadbeat father, J-Jizzy (CHARLES MURPHY), who just so happens to be a successful singer.
The latter needs a hit, however, and thus his manager, Delicious (KATT WILLIAMS), is looking for a new song, and thinks he's found one via Benjamin. Yet, he and J-Jizzy don't realize their connection through Nancy who's likewise in the dark since Benjamin's told white lies about his true vocation.
As the film's narrator (QUEEN LATIFAH) and her nemesis, Bah-Humbug (TERRENCE HOWARD), try to influence things, Nancy and Benjamin begin to believe that they've found true love, unaware of the comedic complications and revelations that lie in wait for them.
