Gabe Kotter returns to his old high school, this time as a teacher. He's put in charge of a class full of unruly remedial students called the Sweathogs. They're a bunch of wisecracking, underachieving and incorrigible students, and it takes all of Mr. Kotter's humor and experience as a former Sweathog himself to deal with his class.

"Welcome Back Kotter" aired on network TV from 1975 to 1979. Each of the episodes in the complete DVD collection is in MP4 format for easy viewing
