A prominent sleep disorder doctor dies in his apartment after reporting a fire; however, no signs of the blaze are found at the building. Mulder manages to get assigned to the case after being tipped off about it, and is joined by a new partner named Alex Krycek. Scully's autopsy finds all of the secondary signs of death by fire, as if the doctor believed he was burning.
A man named Augustus Cole visits an old military buddy, who is subsequently found dead with wounds that suggest gunshots but have no external trauma. Mulder and Krycek find that the doctor, Cole, and the newly dead man were all part of the same Marine unit during the Vietnam War. Mr. X visits calls Mulder to visit him in person and gives him a report showing how the military was looking into ways to remove the necessity of sleep in soldiers, and how the dead men were part of such an experiment.
Mulder thinks Cole, who hasn't slept in 24 years, may have developed the ability to project his consciousness onto other people. Another surviving member of the experimental squad tells the agents that the squad went AWOL and were responsible for a terrible massacre, and that Cole may be seeking justice for those who died.
Mulder and Krycek look for Cole and another doctor who took part in the experiments. They find Cole after he nearly kills the doctor with a vision. Mulder tries to talk to Cole, who is despondent after so long without sleep, but Krycek kills him after believing Cole is pointing a gun at Mulder. The episode concludes with the revelation that Krycek is a plant from the Cigarette-Smoking Man and his cronies.
Tony Todd, who plays Cole, was also the Candyman in a series of horror movies bearing that name. Jon Gries, who plays Salvatore Matola, played Broots for several episodes of The Pretender as well as Roger Linus on Lost.

A few serious wounds aren't confirmed as deaths. And then there were the 4,000-plus confirmed kills Mr. X mentions regarding the experimental squad, presumably including a massacre that kills over 300 people...
"Such figures, while reflecting the tragic cost of war, serve to artificially inflate the tally of investigation deaths and therefore don't count!"
