Following Terminator 2: Judgment Day, Sarah and John Connor fled to Paraguay, until one day Sarah spots a Terminator unit in the town square. A great cat-and-mouse game ensues before she realizes he′s an actual man, an ex-counter-terrorist named Dieter, the man the T-100 will be modeled on. After she tells him her story, he tells her another. He′s discovered that Cyberdyne is still active, and about to create Skynet. So she, John, and Dieter set off to finish the job. But first they must face the most insidious Terminator unit yet, one that can easily pass as human and who has all the resources of Cyberdyne, as well as several Terminators, at its command.

Based on the world created in the motion picture written by James Cameron and William Wisher.
