In a French high school, a group of students finds themselves at the very bottom of the academic scale. Known as the "underachievers," these young individuals are a complete disaster in their studies and are about to face their final exams. The pressure mounts, but instead of feeling defeated, they decide to take matters into their own hands in a very unconventional way. They hatch a bold plan to not only pass the exams but to do so with a touch of humor and madness.
With the help of a somewhat peculiar teacher, who also doesn't have high expectations for his students, the group embarks on a series of hilarious adventures. From creating an elaborate system of cheats to infiltrating the classes of the brightest students, the underachievers showcase their ingenuity and creativity. However, what begins as a clever game soon evolves into a reflection on friendship, perseverance, and the value of self-acceptance.

With humor that challenges conventions and a lighthearted narrative, the film captures the essence of adolescence and the struggle to surpass expectations. In the end, the underachievers learn that despite their differences and weaknesses, friendship and creativity can open unexpected doors in a world that seems to be against them.
