Armand is causing trouble at school again. His eccentric mother (Renate Reinsve) is called to a meeting with the teacher. To her surprise, the parents of another boy are also waiting for her at school. No one there knows what really happened. This (possibly) minor incident between the boys is like a spike that bursts the balloon of tension between their mothers. The conflict escalates, where truth mixes with lies, and the heroines begin a psychological battle for attention and trust.
