Alex (Jean-Paul Rouve) feels as if hes sitting on top of the world -- hes enjoying a successful career as a writer, and hes in love with a beautiful woman, Laeticia (Melanie Doutey) who seems to be just as infatuated with him. But as Alexs romance with Melanie progresses, she gently but firmly insists on a more permanent relationship, and asks him to move in with her. Commitment-phobic Alex is convinced this is the first step towards marriage, and insists on keeping his own flat. Running out of excuses, Alex persuades his agent Jacques (Kad Merad) to feign depression and move in with him, but Laeticia isnt buying Alexs angel-of-mercy act and finally lays down the law -- either they move in together or shes going to leave him.
