Near Ellen's Air Force Base, Southwest Idaho, MP's are outside the Budahaus house. They enter the house in search of Lieutenant Colonel Budahaus. They find Budahaus in his bedroom, he is all burns and shaking violently.
     Back in Washington D.C. Scully is waiting at a bar for Mulder, while looking over some papers. Mulder arrives and he says he has somethi to show her. They go to get a table, Deep Throat ia at the bar watching them. Mulder tells Scully about the case, while ahe flicks through the file. He tells her how Budahaus barrickaded himself in his house and was hospitalized. The military aren't saying anything and missus Budahaus hasn't seen or heard from her husband. Mulder tells hr this kind of thing has happenened to six other pilots enlisted at Ellen's Air Force Base. Mulder thinks there UFO's there flying and Scully says ahe heard they had been shot down in Russia. Mulder gets up to go to the toilet, while he is washing and drying his hands Deep Throat appears in the mirror. He tells Mulder to stay away from the case, that he and Scully are in danger of exposing there work. He also tells Mulder that he is in a position to give Mulder information.
     Scully is in the FBI headquarters looking at microfilms, she rings Mulder at home and asks him if he is taking them on UFO goose chase. Mulder hears a clicking noise on his phone line and looks out the window to see a van parked there. He tells Scully he'll talk to her on the plane, that the line isn't secure.
     Mulder and Scully arrive in Marriette Field, SW Idaho. They go to the Budahaus house to talk to Mrs. Budahaus. She tells them that she first thought something was wrong when Bob, her husband got a rash under his arms. After that things went crazy. He became unpredictable. One time at a dinner party he put fish flakes on his food. She found it hard to talk to him and he would become angry. He would yell at the children for no reason and then start to shake like he was having a seizure. Mulder asked did he talk about his work. Mrs. Budahaus says he never talked about his work even before he changed, but that she heard rumours of top secret work. She says her husband was a patriot and valued his loyalty to his country above all else and now they were being treated like they didn't exist. Mulder asks had this happened to anyone else and Mrs. Budahaus that a friend of hers' husband had gone crazy. They go to talk to her and she says that stressed caused it. Her husband is out the back doing up flys for fishing, plucking hairs from his head to use for the flys. His wife says he got therapy and treatment and was well looked after. She admonishes Mrs. Budahaus for bringing the FBI to her house. They go back to Mrs. Budahaus' house and she gives them numbers to call at the base. Scully tells her that they are staying at the Beech Grove Motel if she needs them for anything.
     Mulder and Scully discuss what could be wrong with Col. Budahaus. Scully says that POW's suffer from the same symptons. Mulder says these pilots shouldn't be affect like that by stress, that they strife on stress not lose it because of it. They go back to the motel and try the numbers. They don't have much luck, Mulder was on hold for 45 minutes and Scully says a Col. Kissel will meet with them a week from Friday. They go to Col. Kissel's house to talk to him, but he won't talk. They are met by a man who introduces himself as Paul and that he is a reporter. He asks them what they're investigating. Mulder asks him where he'd find UFO nuts. They go to a local diner and the woman serving them shows Mulder a picture she took of a UFO out on her back porch and that she'll sell it to him fo $20, he buys it. Scully calls him a sucker and that she'll meet him outside. Mulder asks the woman where he could see a UFO in the area. He meets Scully outside, who tells him the base isn't on her map and Mulder says he knows. He got map to the base from the woman in the diner.
     They arrive at Ellen's Air Force Base and Mulder heads up an embankment to watch the sky, Scully tells him this won't look good on her field report. Later Scully is sleeping in the car when the back windscreen blows in after an aircraft flew low over the car. Mulder comes down the hill and brings Scully up to see the lights in the sky. They watch them dance and fly around, doing manouveurs not possible by ordinary planes. Scully says they're lazers but Mulder thinks they're aircraft. Suddenly the lights disappear with a crash and a helicopter appears. Two teenagers come out through a hole in the fence and Mulder and Scully go after them. They run way from the heliopter and bring the kids with them. They go to a restaurant and have burgers. Mulder and Scully ask them about the base and the lights. The kids tell them about how they've been watching them for a year, that they have a spot where they go to watch them. They also tell them about Yellow Base, where all these aircraft are stored. That one time they saw one hang in the sky and hover for a while and then fly off very quickly. They are being watched from outside by a man in a car. He is reporting their location on a walkie talkie. They boy tells Mulder that the UFO he saw looks exactly like the one in the picture.
    They get a message that Colonel Budahaus is back and go to talk him. Mrs. Budahaus is very upset and claims it isn't her husband. Mulder asks him his date of birth, his kids names and a baseball question, all of which he answers right but when he asks him a technical question about flying, Budahaus doesn't know. This leads Mulder to believe that his memory has been drained of that knowledge. Scully says thats impossible.
