When a hacker downloads decades' worth of classified information about aliens onto a digital tape, he gives it to Mulder, who finds that the entire tape is written in Navajo. Cigarette Smoking Man begins searching for the tape and visits Mulder's father, who calls Mulder to see him shortly afterwards. Before he can reveal anything to Mulder, however, he is murdered by Alex Krycek. Scully brings Mulder to New Mexico, where she introduces him to Albert Hosteen, a code-talker who can translate the digital tape. Albert's grandson shows Mulder a boxcar filled with alien corpses. Cigarette Smoking Man tracks Mulder's location, however, and orders the boxcar burned.
