A rogue comet could spell the end of life on Earth unless Rodney and John can find a way to deflect it.
Rodney hadn't been expecting the knock at the door just after midnight, answering it with a fractious six-week-old baby in one hand, bottle of warmed milk in the other, and three-year-old Madison wrapped around his left leg.
The opportunity to study Atlantis while she rests on Earth seems too great for the I.O.A. to resist, but as far as John is concerned, Atlantis belongs in Pegasus, and Rodney belongs on Atlantis... and if John could have his dreams come true, then Rodney would also belong with him.
When a murder occurs on Atlantis, Woolsey requests a civilian detective to handle the case, and who better than a Vegas detective who already knows all about the Stargate Program. As the investigation progresses, it draws John and Rodney closer together.
