A serial killer is on the loose in Tel Aviv. Each victim is found tied to a chair with a baby doll glued to their hands, the word 'mother' carved into their forehead like a mark of Cain. Stowed away between the wax figurines of the Bible museum where she works, Sheila Heller knows both victims. She suspects the killings have something to do with a pact their group all made at university - to never have children. What Sheila doesn't know is who is committing these gruesome acts of ritualistic violence, and whether she herself might be the next target.
