Zack, Slater, and Screech make plans for a Friday night poker game. Mike nixes the idea of having the game and the guys decide to help him with his love life to get Mike off their backs. They encourage Mike to ask out the English literature professor, Judith Trudell, that he has a crush on. Meanwhile, Kelly, Leslie, and Alex develop a crush on their new karate instructor, John Hammer, and vie with each other to try to win his affections.

After a new professor takes over their Ethics class, the gang faces a dilemma when Zack gets his hands on a copy of the midterm. Meanwhile, Screech covers for Slater at the student union, but soon finds out that bussing tables isn't his forte.
