Mulder and Scully are sent to Chicago after after a telemarketing firm receives anonymous threats. The company is particularly concerned as they had an employee go postal in a different office and wants to avoid another dangerous incident.

Lambert takes everyone, including Mulder, hostage but during the incident Mulder realizes that Lambert may not be the deranged madman everyone is making him out to be. Written by
