Des jours et des nuits.

Richard Deligny (Stephane Freiss) is a successful businessman and everything seems alright in his life - he is happily married, has a loving wife, a beautiful house, a grown-up son who is settled - but he starts seeing this woman in his dreams and progressively becomes obsessed by her. He is convinced that she is not only a dream but really exists and he wants to find her. This will lead him all the way to Greece.
