Lena Katz who is German and David Fish who is American are Jews who live in New York. When Lena's mother who arrives from Germany meets her at a hotel she finds an almost-dead woman lying on the hotel floor. She accompanies the injured woman to the hospital and meets David who is the woman's son. After David's mother dies from the injuries a question remains: was she murdered? The trail leads to Germany. Apparently Lena's mother has some kind of relationship with David's mother that reaches back into the dark German history of the 1940s
