Nekega mrzlega zimskega dne se v šolskem priporu znajde pet dijakov. Med jutrom in popoldnevom se med tujci, ki na videz nimajo prav nič skupnega, kljub začetnim nesporazumom spletejo globoke prijateljske vezi. Sčasoma se ne naučijo le veliko eden o drugem, ampak tudi o samih sebi. Vsak v srcu nosi svojo skrivnost, ki začne počasi prihajati na dan in jih osvobajati. Peterico sestavljajo športnik Andy, upornik John, premožna Claire, vase zaprta Allison in osamljeni Brian… Gre za kultni mladinski film, iz katerega je glasbena uspešnica ‘Don’t You (Forget About Me)’ skupine Simple Minds.
Beyond being in the same class at Shermer High School in Shermer, Illinois, Claire Standish, Andrew Clark, John Bender, Brian Johnson and Allison Reynolds have little in common, and with the exception of Claire and Andrew, do not associate with each other in school. In the simplest and in their own terms, Claire is a princess, Andrew an athlete, John a criminal, Brian a brain, and Allison a basket case. But one other thing they do have in common is a nine hour detention in the school library together on Saturday, March 24, 1984, under the direction of Mr. Vernon, supervising from his office across the hall. Each is required to write a minimum one thousand word essay during that time about who they think they are. At the beginning of those nine hours, each, if they were indeed planning on writing that essay, would probably write something close to what the world sees of them, and what they have been brainwashed into believing of themselves. But based on their adventures during that nine hours, they may come to a different opinion of themselves and the other four.
