After Christian (Claes Bang) divorced his wife, he started a new life with his little daughter (Lilianne Mardon). Christian worked as a curator in an art gallery. Recently, he was planning an installation exhibition called "Square", hoping to promote a positive concept of equality and mutual assistance for all. In an accident, Christian's mobile phone was stolen. Through GPS positioning, Christian found the apartment where the thief who stole the mobile phone lived. Late at night, Christian stuffed a letter of accusation into the door of every household in the building. Who knew that this thoughtless move caused him a lot of trouble. In order to promote the exhibition, Christian found an agent of a media public relations company, but these two unreliable men soon turned the exhibition into a mess. Misfortunes never come alone. A dewy relationship between Christian and female reporter Anne (Elisabeth Moss) made Anne launch a fierce offensive against him.
