Since his wife left him, almost twenty years ago, the once brilliant lawyer Loursat has slumped into a life of despondency and drunkenness. He lives in a vast empty house with his teenage daughter, Nicole, with whom he hardly communicates. One fateful day, something happens which pulls Loursat back from the abyss: he discovers a dead body in his house. When his daughter and her group of rebellious young friends are charged with the murder, Loursat decides to take charge of the case.
