Lola (Christa Theret) surnamed "Lol" is the girl of Anne (Sophie Marceau). Her boyfriend, Arthur, provoked her because he saids, he tromped her with a girl over summer so Lola saids like him ! But it isn't real...
The dialogue in between Lol and Anne is very difficult because Anne views Lola as a kid. For exemple, Anne meets her ex-husband and she meets a police-man. Lola has a life very difficult but fortunately her friends are there for it argue !
