Mulder and Scully investigate an accident that was predicted by an old man who accosted the victim a few minutes beforehand to warn him he would be run over by a bus, which is exactly what happens. The man, a university professor, was with one of his colleagues, Jason Nichols, when the accident happened. The old man was taken into custody by the campus police, but the arresting officer is found frozen to death and mysteriously, is still getting colder. The old man escapes and a visiting Japanese scientist is also found frozen to death. The obvious suspect is Nichols but Mulder begins to suspect that something far more complex is happening.
