Silvia Kaltenbach, single mother of 11-year-old Marc, is just about to get married to Rolf. However, after years of silence, Marc’s father Ricardo chooses this moment to appear. The wealthy son of a South American businessman abandoned Silvia when he discovered that she was pregnant. While her son Marc is very taken with the athletic Ricardo, who she introduces as an old friend, Silvia herself remains skeptical about his sudden paternal interest. But before long, Ricardo has not only enthralled Marc with his spontaneity and lust for life but also manages to awaken memories of a great love in Silvia.
