The X-Files movie, Fight the Future, continues from the time frame of the cliffhanger final episode of the 5th season, with the X-files out of action after the fire in the basement office.
The movie opens in pre-historic Texas, with two cave men hunting down an alien being in an ice cavern.
In the present, a young boy falls through the ground while playing with his friends and lands in the same cavern. As his friends peer down from above, Stevie is attacked by the black cancer, which also infects two firemen who attempt to rescue him and a further two firemen who go in after the first two.
Mulder and Scully, re-assigned off of the X-Files, are inspecting a building opposite the federal building in Dallas after a bomb threat warning, which was made to the federal building. Scully clears the building when Mulder discovers a bomb which shortly afterwards detonates, destroying the building.
The powers that be in the FBI try to pin the blame on Mulder and Scully for the explosion, and endeavor to split up the partners. Scully tells Mulder she is going to quit the FBI.
Back in Washington, Mulder is contacted by Dr. Kurtzweil who explains that the bomb blast in Dallas was part of a cover up by members of the government.
Mulder later learns that the body of a young boy and three firemen were found in the bombed building, which they thought had been cleared. Adding substance to Dr. Kurtzweil claims. His claims are given further credence when Scully's autopsy of one of the firemen and cannot produce a cause of death.
Mulder manages to convince Scully to help him investigate the case as he needs her. They uncover a sinister conspiracy by the shadowy syndicate to aid aliens in there colonization plans and their part in a planned Armageddon that will affect every man, woman and child on the planet.
However, the syndicate is left out, as the black cancer has mutated into a virus that affects humans, using them to create a new alien life form; a virus for which there is no cure, save for a weak antidote developed by the Russians.
Mulder and Scully discover the syndicate's secret bee farm in the desert; bees that will be used as carriers of the deadly virus. The syndicate members take steps against them, kidnapping Scully and shooting Mulder. The syndicate infects Scully with the virus and takes her to a secret installation in Antarctica.
Mulder leaves the hospital with the help of the Lone Gunman and Assistant Director Skinner and attempts to find Dr. Kurtzweil for more information. Instead meets the Well-Manicured Man, who gives him Scully's location and a small amount of the Russian's antidote shortly before he is killed by a car bomb.
Mulder tracks Scully to the installation in Antarctica, gaining entry via a tunnel in the ice. He stumbles across thousands of cryo-tubes containing people infected with the virus, gestating the new alien life form. He locates Scully and injects the antidote, some of which gets in to the system. Mulder and Scully flee the installation just in time as it turns out to be an alien craft. As they collapse at a safe distance, Mulder watches in awe as the craft flies over head and disappears in to the clouds, moments later Scully regains consciousness.
Back in Washington, Mulder tells Scully that she is better off without him and that he refused to watch her die because of his own hollow cause. Scully informs Mulder that she refuses to leave the FBI because if she leaves, "they" win. Rejuvenated, the partners prepare to fight united.
A helicopter lands at the syndicate's new bee farm in the desert in North Africa, the Cigarette Smoking Man steps out and walks towards Strughold. They discuss the new bee farm and the progress of their plans. The Cigarette Smoking Man informs Strughold that Mulder has become reinvested and poses a threat to them. Strughold retorts, 'He is but one man. One man alone can not fight the future.' The Cigarette Smoking Man hands a telegram to Strughold, it reads: "X-FILES RE-OPENED. STOP. PLEASE ADVISE. STOP."
