Needle Boy (2016)

Life has become unbearable for 23-year-old Nick who is convinced that he's an evil person. Consequently, he shows up at the university with a gun in his pocket wanting to shoot his fellow students. But something beats him to the punch; a few hours before his classmates have died in a terrible drowning accident at sea. Nick now stands alone with a gun in his pocket, and he faces 24 dark hours in Aarhus where everyone around him perceives his frustration as grief.
