In failing health, Joe's grandmother Sofia begs him to come visit her one last time for her birthday, and to bring his beautiful wife Tiffany along. Since Joe never got around to telling "Nona" he and Tiffany got divorced, he's forced to beg Mel to pretend to be his trampy ex. Soon, Joe and Mel are on the road to Jersey with Lennox and Ryder tagging along.
Once there, they meet Joe's colorful mother Gloria, his sister Theresa and the formidable Sofia. Sensing something is amiss with her grandson and his "wife," Sofia resorts to trickery to see them repair their marriage by any means necessary. What started out as a silly ruse soon makes a wrong turn, and leaves Joe and Mel confused as to where they stand with each other.
Meanwhile, Joe's nephew Marco makes the moves on Lennox. And Ryder enjoys being treated like a king until he's asked to perform a favor for the family.
