Daniel (Daniel Auteuil) is a best-selling author who writes under a pseudonym, and no reader knows his true identity behind the pseudonym. Daniel's son is about to get married, and the wedding will be held on the Italian island of Capri, where Daniel meets a beautiful woman, Mira (Anna Mouglalis). Under the latter's constant temptation, Daniel forgets his responsibilities and morals as a husband, and the two spend a night together. After returning home, Daniel's heart can't calm down for a long time, because he finds that Mira is none other than his son's newlywed wife, and the successive threatening letters also make Daniel not know where to go. At the same time, an accident at work causes Daniel to reveal his identity to readers, but when these blows come one after another, who will be the ultimate behind-the-scenes mastermind?
