After seeing the initial passion and romance fade into a series of routine and boring relationships, Alexandre (Vincent Perez) concludes that romance ends when sex enters into a relationship. Determined to prevent this from happening with his latest love-interest—a sexy young woman named Fanfan (Sophie Marceau)—he decides that platonic love is the solution. Despite the wonderful, romantic, and inventive ways Alexandre finds for them to spend time together, Fanfan is left disappointed by his refusal to make love to her. Their exciting relationship becomes jeopardized by Alexandre's unwillingness to change his new approach to love.
