Etienne, a private detective, wins the lottery jackpot. But in between having the winning ticket at the bottom of his pocket and depositing the pile of money on a bank account, lies an interval of time in which luck could still change like the wind. For example, if Etienne were to go to a party and swill too much alcohol to the point that his friends forbade him from driving his car, to the point that he took the wrong metro line, to the point that he got into a tussle with punks who stole his wallet… It is about the classic snowball effect. But the avalanche can only be stopped in one way: by dropping to the bottom of the ravine. Therefore, in a few days, in a few hours, Etienne, the virtual millionaire will perhaps see his life topple over several times.
