When an undercover cop involved in a mob investigation goes missing, the BAU believes a serial killer rather than the mob has something to do with his disappearance. The probe leads to several unsolved missing persons cases.
The BAU profiles a serial killer who takes families hostage and lives with them as a father figure during what is supposed to be their family vacations.
The BAU is asked to identify a killer who is shooting at victims in broad daylight, and the team works with local law enforcement officers to recreate one of the shootings.
The BAU investigates the kidnapping of a U.S. District Attorney\'s daughter and determines the kidnapper isn\'t seeking money - he is after her twin sister. The case becomes complicated because the kidnapper is always one step ahead of them.
The BAU travels to San Diego to stop a rapist and murderer who commits his crimes in the middle of the day. The suspect appears to blend into the neighborhood so well the local authorities have been unable to capture him.
Gideon and the BAU track down a copycat bomber who has been terrorizing a quiet community. They determine the bomber is mimicking Gideon\'s nemesis, Adrian Bale, the man responsible for murdering Gideon\'s team in Boston several years earlier.
The team of investigators tries to capture a serial arsonist who has been terrorizing a college campus. Most of the evidence from the fires had been burned beyond recognition, so Gideon and the BAU must rely on psychological analysis to identify the firestarter.
After a fourth woman goes missing in Seattle in a period of four months, the BAU is brought in to track down the abductor before he kidnaps again. Meanwhile, SSA Aaron Hotchner is asked to evaluate SSA Jason Gideon secretly to determine if he is really ready to work full-time again after returning from a six-month leave of absence.
