THE DEATHS OF AN ENTIRE RESEARCH TEAM UNDER STRANGE CIRCUMSTANCES SEND SCULLY AND MULDER TO THE TOP OF THE WORLD TO SEEK OUT A MENACE HIDDEN FOR THOUSANDS OF YEARS IN GLACIAL ICE.
When all five members of an Arctic research team are found dead, Mulder, Scully and a team of scientists seek the answer at a remote Arctic station. There they discover ice samples drilled from the center of an ancient impact crater, holding evidence of a bizarre alien life form over 200,000 years old. Trapped by an ice storm in the tiny station, the team members turn on one another as they are killed one by one. As the increasing fear isolates each member of the party, even Mulder and Scully eye one another with doubt and fear in a tense, angry standoff that tests their relationship. Only a dog and a worm can provide the answer to the riddle and release them from a tightening web of paranoia and suspicion.
