Airdate: August 31, 2001

On P3A-194, SG-1 encounters the Volians, a peaceful agrarian society, who introduce them to the advanced and benevolent race with whom they share membership in an interplanetary confederation, a race which is possibly a formidable ally against the Goa'uld. They are the Aschen. The Aschen are anxious to share their technology in exchange for full disclosure of the stargate network, and negotiations begin between Mollem of the Aschen, and Ambassador Joseph Faxon. Meanwhile, the SGC is troubled to discover that the Aschen homeworld may be in the vicinity of P4C-970, the planet named in the mysterious message that was a warning from the future.

The trade negotiations proceed so smoothly that O'Neill becomes suspicious of the Aschen agenda. Meanwhile, Daniel and Teal'c explore the planet and discover the remains of a buried city, once a flourishing urban community. Daniel is able to partially translate newspapers found there, and learns that the Volians were once a thriving urban civilization. When a flu pandemic killed millions, the Aschen arrived and offered a vaccine that saved their world. They were seen as heroes until it was discovered that the vaccine had a side effect. The urban society abruptly ended, all evidence was buried, and the past was forgotten.

O'Neill tries to warn the President against an alliance, but he is thwarted by Senator Kinsey, who takes the negotiations out of his hands. Faxon and Carter return to the planet, and under the pretense of requesting a translation, they learn the sinister truth behind the newspaper headline: "Vaccine Causes Sterility." The negotiations have been an Aschen ploy to wipe out humanity. Furious at being discovered, the Aschen prepare to send a bio-weapon to Earth, but Carter escapes through the gate in time to give warning and close the iris. The Aschen's only victory is the acquisition of coordinates to a black hole.
