Hijinks run all-round before the last dance of the school as the gang tries to raise money to hold their Senior Prom. But with the gym decorated for a play, Zack proposes a Western-themed square dance. Meanwhile, Zack tries to get Kelly to go with him as a date while Screech tries to find any date, until Lisa feels a little compassion and decides to attend with him. At the dance, Kelly is pursued by student Matt Wilson, while Slater and Jessie end up locked in the boiler room.
