Episode list

While Doggett's investigation of Deputy Director Kersh hits difficulties, the agents encounter a beautiful woman with the ability to remain submerged underwater.

Doggett attempts to uncover the truth about a woman with superhuman abilities who is somehow connected to scientific experiments being conducted in a lab aboard a secret ship that stays at sea year round.

A professor/inmate in a psychiatric ward may be influencing other men to kill ritualistically. Though Doggett sees it as pure manipulation, Reyes can't help but suspect none else but the devil himself possessing the professor's body.

Agent Dogget has been shot and hospitalized. The only suspect is his partner. However, she was 14 miles away when the shooting occurred. The team sticks together to solve the case of being in two places at one time.

Doggett and Reyes investigate a teenage boy who may have the ability to control insects and uses it to kill. Scully and a pushy, pompous, flirtatious entomologist assist them.

Mulder contacts Scully which sets off a chain of events involving an NSA man obsessed with speaking and giving information to Mulder.

Doggett wakes up in Mexico and can't remember his name or what he is doing there. His only clues are small flashbacks of a child (his son) and two mysterious marks on his head.

Reyes finds herself inexplicably connected to a case involving ex-cons who are being skinned.

A man is chased from the Canada/US border and reportedly burned alive though his body is not found. Meanwhile, in the burned remains, the FBI finds papers with the same UFO markings Scully found in Africa.

Scully's baby becomes a bargaining chip for a psychotic UFO cult that feels the baby is ultimately connected to a UFO they have uncovered.

Reyes is seriously injured in a car accident and finds herself in a hospital similar to purgatory with other hospital patients suffering from serious traumas. Slowly they all begin to disappear. Meanwhile, in the real world, Doggett refuses to accept his friend's 'mortal' wounds and uses a bizarre hospital employee to both connect with Reyes in the other-world and capture a 'Dr. Death.'

After thirteen years in prison, a man named Fassl is released and cleared of murder charges when DNA evidence proves he had nothing to do with the murder of an entire family though he was present on the scene. Doggett, who made the arrest, refuses to accept Fassl's innocence and pursues the case again.

Reyes, Doggett, and Scully are pulled into a bizarre serial murder case involving the number '3', numerology on a whole, and an eccentric man who likes to play checkers.

Reyes and Doggett, with the aid of a young Mulder-worshiping FBI agent, investigate a father who is exhibiting bizarre behavior regarding his son who he has kept hidden from the outside world.

The Lone Gunmen, with the (unwanted) aid of Morris Fletcher, must stop a destructive virus from entering the populace.

A disfigured man attacks Doggett trying to retrieve X-Files for Mulder...but he might be Mulder himself.

An eerily brilliant cadet from Scully's class directs Doggett to a current murder case that may have something to do with a case that went unsolved 9 years prior - the murder of Doggett's young son.

Reyes and Doggett investigate two murders revolving around a house that is, at some points in time, identical to the Brady Bunch house.

Mulder's return leads to him being tried for murder before a military tribunal where he seeks to prove the very existence of an alien conspiracy and justify the maintenance of the X-Files.
