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.
