	Synopsis: In an alternate universe, Detective John Sheppard is with the Las Vegas Police Department and begins to investigate a strange series of murders. This Sheppard is a bit down on his luck, over-promoted and barely getting by. What Sheppard is dealing with is a Wraith who has made it to Earth and is building a device to send out a signal of some sort. Of course, he has no idea what a Wraith is but a senior member of the Atlantis expedition, Rodney McKay, decides to take Sheppard into their confidence and tell him about the Pegasus galaxy and their fear that the Wraith is trying to send out a signal with Earth's location. While they succeed, they may have opened a rift with other parallel universes. This Dr. McKay, who is cool and smooth, actually visited Atlantis in another dimension once and wonders what may now happen there.
