Synopsis:

Olja is a high school history professor, young, ambitious and interested in alternative methods of education. She is married to a painter, whose latest exhibition provoked a heated public reaction, because the nationalists considered it to be an insult to the Serbian people. A group of Olja’s students sees this as a reason to attack her. They assault her in a parking lot, their faces covered in ski-masks, pouring red paint over her. They film this and then upload the video clip to YouTube. The next day Olja discovers that some of her students are responsible for the attack. She takes away their mobile phones, and in the heat of the moment decides to lock them in the school building, also disconnecting the school phones and Internet. That night will forever change their lives, attitudes and thoughts.
