Lycée of Jules Ferry is the worst in France. Its advancement results are so low that the school gets on the verge of closure. The only chance to save the school is not to fail the exam, for what high school students are determined being rare loafers and dolts. To avoid embarrassment, the director calls the reinforcements: the troops of zany teacher who are not much better than their students. Among them there is a brutal jock Eric (physical education teacher), a crazy fat lady with a chainsaw Gladys (an English teacher), a fanatical experimenter Albert (a chemistry teacher), a sexy chocolate Amine (a French teacher), a harmless thug in a Napoleon’s suit Poloshon (a history teacher), and a teacher of an unidentified subject, a fan of smoking weed and talking about this and that – a nihilist Kutiro. If the best solution is the worst teacher, how will they pass the exam?
