 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.
