Red's mother spends a Sunday with them and drives everyone crazy, except Fez. She seems to have a certain fondness for him.

Red gives Eric 40 bucks to buy a Christmas tree and says that he can keep the change for his party. So Eric, Hyde and Kelso cut down a tree off the interstate and keep the money. They spend the money on beer and Kelso buys Jackie a Christmas present. Laurie spikes the punch with rum and Jackie's friend's are all attracted to Fez all of the sudden. Red has to work on Christmas Eve and not long after he gets home cops show up at his door telling him that his Christmas tree was illegally obtained and that they have to confiscate it. Also Hyde has a thing for Donna.

Red's mother Bernice has once again managed to make everyone miserable during one of her visits. While driving his grandmother home, Eric lashes out and tells her that it wouldn't kill her to be nice once in a while. Bernice promptly drops dead, leaving Eric to think he killed her. The entire Forman family (including Laurie and Red's brother Marty) comes together for her funeral while Eric gets drunk at a bar with the guys.

The gang, looking for something fun to do on Halloween, revisits their old grammar school, where they find their permanent records. Looking through them, they find out some interesting things about each other. Fez discovers trick or treating.
