In the summer of '68, Leon Dor (Antoine L'cuyer) comes close to hanging himself accidentally. His mother saves him at the last minute, just like last summer in the pool and like two years ago in the freezer. At ten, Leon has lots of problems and an overly fertile imagination. There is Mom (Suzanne Clment) and Dad (Daniel Brire) who are always fighting and those annoying neighbours who get to spend the summer at the beach. And then, there's Lea (Catherine Faucher), the exasperating girl  who's always right about everything. When Mom decides to leave everything behind to start a new life in Greece, Lon is prepared to do anything to kill the pain - destroy the neighbours' house, become a professional liar and even, why not, fall in love with Lea. Together, they will overcome the pain of growing up when you feel abandoned.
