From the booklet: Mark Snow has the best job in television, though he might tell you otherwise during a particularly hellish work-week -- scoring both "X-Files" and "Millennium" for Chris Carter. But the reason we are to admire and not pity this protean musical laborer is that he composes music for stories that depend on mood and atmosphere in a way that your average cops 'n' killers shows don't.
A taller order by far than composing a "Symphony to Book Suspects By," the "X-Files" asks for musical expressions of awe, mystery, wonder and, yes, terror.
Snow furnishes the emotional backdrops with a spare Zen-like palette -- alone cello here, a pensive piano figure there. But, buyer beware: What you hold in your hand is Snow Unchained, his filigree brushwork traded in for buckets of splashy color, his customary restraint eschewed in favor of supernovas of exploding sound.
Big-screen or small, Mark Snow's music is the sound you hear in your head when the picture fades to black. It is the stuff of dreams, the soul's soundtrack.

The descriptions belong to the scene in the movie.

Threnody in X - Opening credits roll by... The second part belongs to the scene where Mulder and Scully are chasing the truck.

BC Blood - Scene opens 35,000 BC in caves where the original inhabitants of earth are dying off and the black oil is first seen.

Goop - The cave scene with the boys. Stevie falls in, discovers the skull and is overtaken by the black oil.

Soda Pop - Our heroes are introduced in Dallas investigating the Federal Builiding Bomb threat. Establishes some back story. Scully is thirsty and Mulder goes to a Soda machine to get one for her.

Already Dead - The agents discover some strange things in the Federal Building that they are searching across the street from the main focus. All the people there are mysteriously dead. Scully and Mulder wheel a body into a lab and some interesting developments are found. Proof undeniable of extraterrestrial viruses.

Cave Base - Intro of CSM and the clean up operation of the cave where boy fell in. More backstory and the establishment of who CSM really is.

Remnants - Building explodes nearly killing M&S... they are made out to be the scapegoats of the disaster by not looking for the bomb, going off on some crazy tangent of Mulder's. All proof that Scully has discovered is disavowed. Scully is offered the deal. Save yourself and survive... or go down with Mulder. Scully says no way... I quit.

Fossil Swings - Back at the site of the cave and in London with the elders. They see M&S from the taped footage and know they've seen too much.

Plague - The famous bar scene with Landau's character appearing, telling Mulder about the plague to end all plagues. Mulder is drinking heavily and offers more backstory for the audience. Unable to believe him completely, the information is making sense and is literally sobered up by the news.

Goodbye Bronschweig - Bronschweig enters the cave and finds out that the alien has left the body. He is overtaken by the mutated alien form and left in the cave by his co-workers.

A Call to Arms - A semi drunk Mulder shows up at Scully's late. She asks him if he came to talk her out of quitting. He tells her to get dressed, there is something she needs to see that might help them get out of this mess. Dr. Alvin Kurtzweil tells him something.

Crossroads - Scully debates and gives in going with Mulder. Owing him at least this. They come across the other three kids and get their story's leading them to the site.

Corn Hives - They find the facility, with white domes and the bee hives out in a corn field.

Corn Copters - The bees attack M&S and they run through the corn fields barely escaping, but without the critical evidence needed to verify their story and being chased by two black helicopters.

Out of Luck - Back in DC, at Mulder's. Scully tells Mulder this is it, she cannot follow anymore. Their partnership is over and they have finally run out of luck. A desperate Mulder tells her that they are close and he needs her. It is a bittersweet scene as Scully refuses. He can't deny her any longer, seeing as how her career is ruined.

Stung Kissing/Cargo Hold - As Scully leaves his apartment, her emotions close to the surface, Mulder opens the door to his apartment. Scully stops... turns around to see the look on his face. Telling her that if she were to never walk through his door again... he is overwhelmed and can't continue. Near tears, Mulder and Scully walk towards each other one last time and hold each other. Pulling back to look in her eyes, he cups her cheek. She mirrors his action. A deep and meaningful look at each other says more in five seconds than has been said during the entire past five years. As they start to kiss, mere milimeters away, a bee that was trapped in Scully's collar, from the bee hives, finds its way out and stings her in the neck.
Falling back in pain, Mulder recognizes the bee is one from Texas and is probably carrying the virus. As Scully collapses, he calls for the Paramedics. They arrive and as Mulder is trying to get info from the driver on where they are taking her, the driver shoots him in the head, just grazing his temple.
The next scene is Scully being put in some kind of pod and being put on some kind of cargo plane bound for the Antartica.

Come and Gone - Enlisting the help of TLG and Skinner, Mulder is able to escape the hospital and put in the call for help. Kurtzweil is "Come and gone".

Trust No One - Mulder finds the WMM. Fearing the alien colonists are stepping up the project with a mutated virus to fight the vaccine they Elder's have developed, the WMM helps Mulder by telling him where they took Scully.

Ice Base - Surveiling the ice base in the Antartica, Mulder finds a way in by accident falling down a chute through the ice.

Mind Games - ???

Nightmare - ??? (Possibly the view and whole running in the base.)

Pod Monster Suite - Mulder finds Scully half-naked in an alien pod full of strange green liquid we've seen before. This is the big action event of the movie, being chased from the ice base, the huge alien spaceship below the ice starts to warm up causing a gigantic sinkhole effect. While carrying/helping Scully they both fall in and Mulder is knocked unconscious briefly as the spaceship takes off...

Facts - The scene before the ending, the last one with M&S.

Crater Hug - The spaceship gone, they are left on the in what remains the shell of where the spaceship was. Mulder and Scully realize they are left drawn closer together, alone to fight the future of what is about to come to pass sending the future of the X-Files into a whole new direction.
