In Knoxville, Tennessee, a mysterious train car is left in a rail yard. After dark, a group of Japanese scientists enter the car and conduct an autopsy on an alien body. The scene is recorded and transmitted via satellite. Suddenly, a strike team storms the car and kills the scientists, taking the alien corpse away in a body bag. Fox Mulder (David Duchovny) purchases an edited video of the autopsy. He believes the tape is authentic, but Dana Scully (Gillian Anderson) is skeptical.
