Lonely medical student Frank enjoys the solitude of his apartment, ideal for studying for his upcoming exams. However, his peace is shattered after encountering Lotte, the chatty girl living upstairs, who leads him to suspect something is amiss in the building. Each departure from his flat becomes a source of anxiety as he faces a cast of unsettling characters: a nosy concierge, an irritating child, the clingy Lotte, her violent ex, and especially her menacing new boyfriend, Micke, who seems intent on making Frank's life a nightmare.
