Although Marie has always cooked the traditional turkey dinner for Thanksgiving, Debra decides it's her turn to prepare the holiday meal, but, not wanting to compete with Marie's turkey, she chooses to serve fish which upsets the apple cart. Marie, feeling threatened when her family thinks Debra's fish idea is perfectly acceptable, decides to bring her own turkey to the dinner party to prove that she's the better cook. Meanwhile, Ray's idea of a traditional holiday at home becomes even more untraditional when the relatives opt not to watch football.

At a big surprise party for Frank and Marie's 40th wedding anniversary, Raymond is shocked to learn that his parents were once separated for a year and might have gotten divorced if Frank hadn't returned home to help with Ray's broken arm. After the initial shock wears off, Ray starts to wonder if it's his fault that his parents are still together... and miserable.

When Ally has to do a school project on genealogy and interview her oldest living relative, Ray helps her track down Frank's long-lost Aunt Sarina, who lives in Italy. But apparently the unmarried Sarina has taken "stop by if you're ever in America" a little too literally and shows up at the front door. Her American family instantly adores her for her way with pizza and old-world charm. Ray, as always, thinks it's too good to be true and he's right.

While the Barones prepare for a friend's wedding, Ray kiddingly asks Debra, "Why did you marry me?" When she hesitates, he flashes back to the not-so-magical night 10 years before when he popped the big question. Ray gets unexpected, unsolicited and unwelcome help with from his parents, but Debra says yes anyway. That leaves the gloomy groom wondering if she did so because she loves him or because she felt pressured. So, Ray decides he's "gotta give her another chance to say no."
