Sheppard's team goes check on the Tarantians (whom they rescued away from the super-volcano), who stopped answering calls, and find the village totally deserted. They follow McKay's sensors detecting life in the subterranean system left by an extinct civilization and stumble upon a pile of Tarantian corpses with identical cranial incision, next a lab with an Iratus bug. Ronon barely survives an attack by a giant super-bug, cutting off an arm, and Weir sends a team of Marines, who go missing, only for their mutilated corpses to be found similarly horded. The team meanwhile discovers hives of aggressive super-bugs, and their creator: none other then Michael Kenmore, whom they gave access to science improving on Wraith technology after being rejected by them as impure. The team must survive and trick Michael, who sabotaged the Stargate by stealing the control crystal, stealing his own dart-glider.
