Felix, now in his late twenties, always knew that he would get married at some point. Now he is convinced that he has found the woman for life in his long-time girlfriend Fabienne. But no sooner has he persuaded Fabienne not only to marry him, but also to have a romantic wedding with all the trimmings, than the preparations for the big event turn out to be an explosive minefield. Surrounded by to-do lists and discussions about family names, the inevitability of events sends Felix into a panic. Suddenly all the women seem to be smiling at him invitingly, and when the fascinating Johanna reappears in his life, Felix cannot resist the temptation. He wonders whether it's really just a guilty conscience that drives him to tell Fabienne about his infidelity between the registry office and the altar.
