A deadly, flesh-eating bacteria has put Global Dynamics on biohazard alert. As a protection mechanism, Allison's (Salli Richardson) office has plunged a mile underground. Not an ideal situation given that Allison and Kevin (Meshach Peters) are being held captive by Henry (Joe Morton) and Beverly Barlowe (Debrah Farentino) in Allison's subterranean command. Since General Mansfield (Barclay Hope) hasn't been able to make contact with Allison, he appoints Nathan Stark (Ed Quinn) acting director of Global Dynamic (GD) and gives him two hours before all organic matter, including people, in the complex will be 'thermally cleaned'... destroyed, to prevent further contamination. Carter (Colin Ferguson), Stark and Taggert (Matt Frewer) suit up and head back into GD. Meanwhile, Beverly and Henry inform Allison of their plan to take Kevin, who they now know embodies the Artifact and is the conduit for the Akashic Field, which embodies all of the mysteries of the universe. Fargo (Neil Grayston) arrives at the Smart House, where Zoe's party is in full swing, in order to use S.A.R.A.H's computer to access the GD computer. He and Zane (Niall Matter) make contact with Carter, Stark and Taggert, just as the sensors that monitor their biohazard suits show that Stark's has been compromised ... and then a photon array set to protect the facility's lock-down starts firing at them.
