On the last day of school before summer vacation, physical education teacher Freddy is preparing to leave on a vacation to Hawaii with his girlfriend, Kim. Vice principal Phil Gills informs several underachieving students, including easily distracted Pam; "nocturnal" Larry, a male stripper; football jock Kevin; pregnant Rhonda; geeky Alan; dyslexic Denise; intimidating Jerome, and two horror-film-obsessed underachievers, Dave and Francis "Chainsaw", that they must attend summer school for remedial English.
