Quick recap
In 1999, four years after T2, Sarah and John are in hiding when the Terminator Cromartie shows up to kill the boy. He's saved by Cameron, a reprogrammed Terminator who looks like a teenage girl, sent back by future John. The three jump forward to 2007, where they learn Judgment Day wasn't stopped, only delayed. Now they hunt the building blocks of a future Skynet, like the Turk, a chess computer built by Andy Goode. Derek Reese, a soldier from the future, and FBI agent James Ellison, who slowly realizes Sarah isn't crazy, both help and complicate the mission. Sarah also fears she has cancer. The season ends with Cromartie killing about 20 FBI agents and Cameron caught in a Jeep explosion.
