My Best Friend

It takes a lifetime to learn the meaning of friendship... François has 10 days.

Catherine refuses to believe that her business partner, the unlikeable François, has a best friend, so she challenges him to set up an introduction. Scrambling to find someone willing to pose as his best pal, François enlists the services of a charming taxi driver to play the part.
