The FBI team concentrates on an unusual case. A Psychiatric patient, the former Dr. Theodore "Ted" Bryar, who was accompanying his female therapist to a congress in Dallas hijacked a whole train in Texas. Coincidentally team member Elle Greenaway in on the train on her way from a prison interview. Ted has complex delusions, notably an imaginary microchip he wants removed from his arm. He also refuses to talk to anyone below the highest authorities and uses his gun. The team also investigates the hostages, in order to understand the dynamics on the train, which the apparently failed therapist cannot be expected to handle. Dr. Spencer Reid is determined to go in for once and perform a manual magic trick to make Ted believe the chip is extracted.
