On a trip to Poland, the shy cemetery worker Eugen wants to meet a woman for money, but then he surprisingly meets the pretty Polish girl Groschka. Eugen is blown away and decides to return to Lake Constance at home with Groschka. Groschka also fits in well, as she is on the run from the police. However, Eugen's jealous and spirited mother is already waiting in Germany, with whom Groschka has to come to terms. But that's not the only problem, because little by little some of Eugen's fellow travelers are found dead.
