Detective Darby McCormick investigates the brutal murders of college students. The girls did not know each other, but the circumstances of their death coincided: a mysterious abduction, a long - several months - stay in an unknown place and, apparently, in a fairly comfortable environment, and then a merciless shot in the head... Who did it: a serial maniac - killer or ecstatic believer? Or maybe the secret is hidden in the distant past? And what punishment does the criminal deserve?
