At the National Radio Astronomy Observatory, two technicians notice irregular frequencies in the night sky. As one technician tries to decode the message, the second technician, named Anthony, shoots him in the head.

At a children's park, Dempsey and a matron watch children playing. Dempsey points out one girl in particular and says she'd be perfect. The matron agrees to kidnap the little girl and says that more extract will be waiting for Dempsey later.
