Join the graduating class of William Ocean High School as they live through their final senior year and experience the fun, the heartbreak, the loves and the loneliness of growing up ... all set to the biggest hits of the 80's. 

Back to the 80's tells the story of the senior class of William Ocean High School that graduated in the 1980's, as remembered and seen through the eyes of Corey Palmer, who is now 30-something. The then 17 year old Corey is madly in love with his next door neighbour, Tiffany Houston, one of the coolest girls in the school. However, she barely notices this as she is too busy mooning over Michael Feldman, the hottest guy around. 
Michael and his friends are athletic and good looking the kind of guys that Corey and his two best friends dream of being. However, while they may not be the coolest guys in school, they are still one up on Feargal McFerrin ru, whose best friend is his computer and who believes the crazy notion that one day CDs will replace cassette tapes. 
The year commences with Class President elections. Michael steals Corey's election speech and when he uses his ideas and promises the girls a kiss for his vote, he becomes President, with Tiffany as his Vice President. 
Meanwhile, the teachers are having issues of their own. Mr Cocker, after being in a relationship for two years with the apparently conservative English teacher, Miss Sheena Brannigan, confiscates an old edition of Penthouse from a student, only to discover that his girlfriend is the centrefold. How will he cope? Will their relationship be able to survive this hurdle?
