It's homecoming weekend. Leslie's parents come to visit her. She is sick of their controlling ways, so she asks Screech to be her date in order to freak them out a bit and Screech agrees to be especially geeky for this event. Meanwhile, Zack is invited to a homecoming banquet by the guest of honor, a football star who could help him score in some business. Also Alex and Slater become closer while training for the role of the university mascot.
