On the eve of his Hawaiian vacation, irresponsible high school teacher Freddy Shoop (Mark Harmon) is forced into teaching a summer-school class. His students are all malcontents and layabouts with the standard repertoire of teenaged hang-ups and hostilities (two of the kids, who can't see enough slasher movies to suit them, are hilarious precursors to Beavis and Butt-Head). Harmon would rather spend his time with history teacher Robin Bishop (Kirstie Alley), but she doesn't think much of his laziness and lack of dedication. Shoop finally begins to take his job seriously when he realizes his students' problems are not all of their own making.
