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.

Fanfan is a young handsome peasant. He joins the army to escape marriage because a gypsy girl predicted he will get glory and the king’s daughter as a wife. But the gypsy girl was in fact Adeline, the daughter of the recruiting officer. Once he has discovered the stratagem, Fanfan refuses to forget this dream and decides to fulfill the destiny of the fake prediction.
