Mulder and Scully investigate a accident that was predicted by an old man who accosted the victim a few minutes before 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 students, 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 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.

If Lucas Menand never gets hit by that bus, his complaint gets heard before the grand committee, Jason Nichols loses his funding and he never gets to collaborate on his research with Dr. Yonechi. Therefore, this photograph never gets taken because this celebration never happens.
