The rebellious IIIB crew and their unconventional teacher Jan Sienkiewicz are back! Love, troubles and school dramas make up everyday life of Dante, Nel and the whole gang. It is joined now by a young mathematical genius - Korek. The guys intend to teach him how to pick up girls, but it turns out that their know-how is rather theoretical…

Dante struggles to reconcile his dreams with reality, while his relationship with Nel is tested. Then the mysterious Adam appears. In the background: the return of Korek, new feelings for Cegła, and the question of whether loyalty, friendship, and love can survive in the adult world.
