Welcome Back, Kotter plot
Gabe Kotter returns to his old high school, James Buchanan High, to work as a teacher. He is immediately assigned a class with a bunch of unruly students. Nicknamed "sweathogs," these students are in this class together as punishment for getting themselves into constant trouble. The troublemakers' club is led by Vinnie Barbarino, who has a knack for rhyming insults. Gabe Kotter has his hands full with these unguided projectiles and tries to guide them as best he can.
