The Infiltrator is dead. The Terminators destroyed. But the war is far from over. Severely injured and recuperating in a military hospital, Sarah Connor discovers some shocking information. Meanwhile, John Connor, aided by the former counter-terrorist Dieter von Rossbach, begins a desperate campaign to prepare humanity for the dark times ahead. For the future does not look good. The fledging Skynet - the sentient computer network that will destroy the world; the network the Connors thought they had finally stopped for good-is up and running, with the full support of Cyberdyne Corporation. And, unbeknownst to the Connors, another Infiltrator Terminator unit has begun its own clandestine operations.
