Mr. Feeny assigns his class a paper on the conflict between the Hutus and Tutsis, which he says is based on class differences between the "haves" and "have-nots". At the end of class he announces the winner of the food drive; Cory and Shawn. Every year, the two turn in cans that the food bank gave Shawn's family the year before. The prize is a turkey and a box of stuffing. They can't decide who gets what, so they propose the first ever Hunter-Matthews Thanksgiving celebration.
Meanwhile, Frankie's brother, Herman, courts Morgan.
Neither family wants to participate, but the boys insist. When Thanksgiving comes around, the Matthewses make the trip to the trailer park. Both families are extremely uncomfortable; Cory's family is nervous and Shawn's family is defensive.
The members of the Trailer Park Homeowners Association ask Chet to step outside. They see the Matthewses as condescending, and they want him to get rid of them. Inside, Chet tries to hurry everyone along, making the situation worse. While the kids are bringing Morgan to Herman's trailer, the adults agree that the whole arrangement was a mistake.
Meanwhile at Frankie's, Cory and Shawn explain what's going on. Frankie likens the families to the Hutus and Tutsis. Shawn says he's glad that he and Cory are ignorant, and "don't know any better" than to be friends. Frankie invites them to eat with him and his brother; "There is always room for more at our table."
The adults watch from the background, as the kids go around the table, saying what they are thankful for. Cory is thankful that his parents raised him to like people for who they are, "even if they weren't lucky enough to be raised that way themselves." The adults feel bad about the way things came to pass. They decide to give it another shot and join the kids at the table.
Back at school, Shawn gets an A+ on his paper. Mr. Feeny calls the work, based on the Thanksgiving experience, the best Shawn's ever done.
