Vienna. Standing at the door of the Tanneks' villa is 15-year-old Emil, who asks for Dana Gan. Dumbfounded, Daniela Tannek slams the door in the stranger's face. She tries to hide her dismay from her soon-to-be-divorced husband Franz and daughter Paula. But the young man won't give up until he is sitting with "Aunt Dana," as he calls Daniela, in her car on the way to her native region, which she hasn't seen since her kindergarten days: Romania's Danube Delta. Neither Franz nor Paula knew about Daniela's actual origins.
