Marty and Debbie are hoping for an uneventful Thanksgiving, but their hopes are dashed when Marty's father arrives with a suitcase and informs the family that, after fifty years of marriage, he and Marty's mother are getting divorced.....and, oh yeah, he's moving in. Jackie's parents arrive from Zabvron just in time to witness the fallout and learn about the peculiarities of human relationships.

Meanwhile, thinking gifts are the emblem of how you truly feel about someone, Reggie and Amber both struggle with getting each other the perfect gift.
