Airdate: April 27, 2007

Hoping to expand the range of Merlin's phase-shift cloaking device, Carter is running tests when she and the contents of the lab are unexpectedly drawn into an alternate universe. There, her counterpart had been attempting to extract energy from parallel universes, but had been killed in the accident that had pulled Carter through. In this reality, General Hammond commands the SGC, and Hank Landry has been president since the attack by Anubis three years ago had revealed the stargate program to the world and forced the government to declare martial law from its base at Cheyenne Mountain. Not only that, the Ori have attacked Earth and will return within five days.

Carter's research might provide the means to defend Earth from the Ori, and Hammond offers the resources of the SGC to return Carter to her own universe in exchange for her help. As five Ori ships appear in orbit, Carter and Dr. Lee draw upon the US power grid to activate Merlin's device and expand the inter-dimensional field to shift the entire planet out of phase. Ori weapons fire passes harmlessly through the planet, and Earth is spared. For her role in saving Earth, Carter is hailed as a hero by President Landry, who presents her at press briefings and formal receptions, but also detains her in an attempt to secure his presidency.

As Carter comes to recognize the loss of freedom under martial law, she turns for help to Rodney McKay, her ex-husband in this reality, and to Cameron Mitchell, now an embittered alcoholic veteran confined to a wheelchair. Despite their warnings, Carter uses her position to speak out about the need to restore civil liberties, but she is quickly silenced by the administration, who finally decides she is more of a liability than an asset. At last, Landry permits her to return home, and with McKay's help she recreates the inter-universal bridge. Urging McKay to be the voice of change after she has gone, Carter returns to her reality from the world that might have been.
