Lena is a bright, disabled girl who, after years spent studying at home, is keen to get back to school. She is assigned to a special class for disabled pupils who have to present themselves before a school commission at the end of the year in order to prove that they merit being moved back into a "normal" class. Her enervated teachers, however, show absolutely no desire to motivate the students and help them improve; on the contrary, they try to quash right from the start any interest Lena shows in more complex study material. Nevertheless, Lena soon involves herself in the school routine and gets together with classmate Anton. Yet their transparent happiness is not to everyone's liking and repercussions soon follow. 玛丽娅·波耶扎耶娃并不是一个没有演技的傻姑娘。站着成长。 故事发生在俄罗斯某中学改造班，那里专门收容生理或心理上非主流的学生。行动不便的美少女丽娜来到这一班，轻易融入其中，还带头到处捣乱和顶撞老师。她引发荷尔蒙旺盛男生的争夺战，失控的学生没有最坏只有更坏，成长的代价超乎想象。
