Merry In-Laws

Raised by an astrophysicist father and psychologist mother, ALEX SMITH was taught the "realities" of life from a very young age. Doing what they felt was best, her parents crushed her belief in all things magical…from the Easter Bunny to the Tooth Fairy and of course Santa Claus. But, as life would have it, she discovers her in-laws are non other than Mr. and Mrs. Clause (George Wendt, Shelley Long.)
