In this episode, Grace and Olivia discuss the crimes committed by one of the Soviet Union's worst serial killers, Andrei Chikatilo. Known by some as the "Butcher of Rostov," Chikatilo sexually assaulted, murdered, and mutilated at least fifty-two women and children between 1978 and 1990. Even though he was formally convicted of fifty-two murders, Chikatilo has claimed to have taken the lives of over fifty-six.
