Because the late Berlin artist Dorn failed to pay his taxes or inform the family for years, his widow Erika and daughters must urgently sell the splendid estate in Tuscany they hardly visited since his death anyhow. Eldest daughter Valerie, junior partner in fiancé Andreas Imdahl's rising architects firm, travels ahead to negotiate with the suitable candidate Robert Beck, a fellow German, who agreed through mayor-publican Fredo to keep caretaker Antonio 'Toni' Gianni. By the time Andreas arrives, he finds Viviane unfaithful with her study lover Stefan Korten, but is interested with Toni's daughter. Second daughter Susi and her fellow arts student fiancé Bruno Tomasi have several announcements. Mother arrives, stating she decided to sell the Cologne home instead, but Robert offers an alternative.
