Adilkhan Yerzhanov had his brilliant Steppenwolf at last year’s IndieLisboa and now returns with Cadet, with this film being a gesture that changes the pace from the dystopian westerns of the director’s past. Also returning is Anna Starchenko, who plays Alina, the mother of Serik, a shy boy who is bullied by his classmates and teachers in a military school where violence haunts every corridor.
