Mark and Joanna met while traveling for Europe with hitchhiking. They live together a period of great happiness and then marry. Marriage determines changes in their relationships and behaviors. Mark, who has become an architect, is progressively heading towards a brilliant career in ever-increasing professionalism. The work that he performs and to which he attributes too much importance, the enviroments more sophisticated and high-society style that he with his wife attend, the boredom that seems to wrap this kind of life are elements that take to a fracture that is increasingly deeply opening up in marriage life of the young couple. Mark has an adventure during the absence of his wife, and Joanna, disappointed by her husband's attitude, when she meets a fascinating, young-looking young man she let herself go. Their marriage is on the verge of breaking, but a serious rethinking of the significant moments of their past leads them to reconsider their lives and to realize how strong the bond is.
