Nusa (Masa Derganc), every student's favorite teacher, goes on maternity leave and is replaced by Robert. Robert is everything that Nusa isn't -- a man who believes in rigid authority and an older style of teaching. A private meeting with a struggling Sabina (Dasa Cupevski) sends her out of Robert's office in tears, and it is the last memory her classmates have of her. Sabina later commits suicide, and the class, left struggling to comprehend their own emotions, squarely places the blame on Robert.
Rok Bicek's debut feature-length film, Class Enemy, is an interesting exercise in grief, and Bicek undertakes the painstaking task of showcasing how it hits the cast of characters differently. Luka (Voranc Boh), who has just lost his mother, uses Sabina's death as a way to shield himself from his own pain. Mojca (Doroteja Nadrah), Sabina's best friend, blames Robert as a way to avoid the reality she had no idea her friend was in such a spot. Spela (Spela Novak), sees Sabina's death as a symbol of everything that is wrong with the school. As pressure starts to mount from his rebelling class, Robert has to wishstand even more from the school's administration, who feel that he is losing control of the people he doesn't really know in the first place.
