In a live news report, a high-speed car chase comes to an end in the
Nevada desert. Assuming it to be a
kidnapping, police pull the female passenger from the car and place her in the back of a police vehicle while her husband, Patrick Crump (
Bryan Cranston), is handcuffed. The woman begins violently banging her head against the police car window. As the news chopper catches all of this on film, the woman's head explodes, sending a spray of blood across the window.
FBI agents
Fox Mulder (
David Duchovny) and
Dana Scully (
Gillian Anderson), investigating possible
domestic terrorism in
Buhl, Idaho, get wind of the bizarre car chase. Mulder coerces Scully into taking a detour to
Elko, Nevada, on a hunch that this may be an
X-File. Meanwhile, Crump, who has started to develop symptoms of a sickness, is put in an ambulance. Mulder, wishing to speak to Crump, follows the ambulance, only to end up being kidnapped by Crump when he escapes police custody. Mulder realizes that Crump is suffering from a painful sensation of pressure building in his head and that the only way to alleviate his symptoms is to drive west. Scully initially believes that Crump is suffering from some sort of
infection, taking a
hazmat team to investigate the Crumps' home. There, she finds a dog suffering similar symptoms and dead birds on a neighbor's property, although the neighbor herself, who is
deaf, was unaffected. Scully then discovers that a
United States Navy antenna array emitting
ELF waves stretches beneath the Crump property. Scully deduces that an abnormal surge in these waves somehow caused a rising pressure in the
inner ear of the nearby inhabitants. Westward motion and an increase in speed seem to be the only thing to help ease the pain of the increasing pressure. Initially, thinking that the FBI agent is part of a government conspiracy, Crump forces Mulder at gunpoint to drive, trying to provoke him along the way with
antisemitic remarks. Eventually, Mulder and Crump make amends and attempt to work out a solution before it is too late. Mulder explains to Crump that Scully will meet them at the Pacific Coast, the end of the highway. There, she will insert a needle into Crump's inner ear, hopefully relieving the pressure. However, by the time Mulder meets Scully and the police at a beach in
California, Crump has already died from his condition. Back in
Washington D.C., Mulder and Scully are reprimanded by Assistant Director Kersh for straying from their original assignment and amassing large debts during the Crump investigation, and are forbidden from investigating any further X-Files cases. ==Production==
