The film is about a school where only 12% of students graduate, and the principal is threatened with closure if 50% of students do not graduate that year. To solve this problem, the principal hires the worst teachers in the city, who use unorthodox methods to teach their students.
These teachers include Miss Gladys, an aggressive English teacher; Q Tiro, a lazy teacher; Eric, a sports teacher; Mr. Albert, a chemistry teacher who performs dangerous experiments; Maurice, a philosophy teacher who speaks in outdated phrases; and a teacher who is obsessed with flirting.
Despite their unorthodox methods, the teachers create chaos at school, and the students' parents complain to the principal. However, the principal allows the teachers to continue their methods, and eventually, the students become celebrities due to their teachers' antics.
When the final exam approaches, the teachers try to help their students cheat by stealing the answer sheet. However, they steal the wrong sheet, and the students are left to study hard for the exam.
In the end, the students pass the exam with 49% passing, but the school is still at risk of closure. The principal comes up with a plan to expel a student who failed, which raises the passing percentage to 50%. The student who is expelled is Bullard, who is known for causing chaos.
The film ends with the teachers being congratulated by the inspectors and being allowed to transfer to any school they want. However, they choose to stay at the current school. The principal is transferred to a new school, and the teacher who was obsessed with flirting finally gets a kiss from the German teacher.
