The deep affection between mother and daughter is a network slang term that many young people are familiar with. The English original means "laughed myself to death" or "laughed myself unconscious". It's also the nickname of Lola's friend, Krista Tretter. At the beginning of the movie, as a new school year starts, Lola suspects her boyfriend Arthur has cheated on her during the summer vacation. Her group of friends makes things even more complicated. To make matters worse, the relationship between Lola and her mother Anna (Sophie Marceau) is strained - they can't communicate at all. Deception, arguments, and mutual misunderstanding are everywhere, which signifies the generation gap. Perhaps it's because their parents' divorce has made family relations no longer simple. The collision between the world of adults and teenagers, the love and estrangement between mother and daughter, where will the relationship go after a series of explosive laughter or infuriating events?
