Plot summary

In a grim 2018--in the wake of Skynet's devastating Judgment Day that claimed the lives of billions in Terminator 3: Rise of the Machines (2003)--the original leader of the Resistance, General Hugh Ashdown, and a now-grown-up John Connor call for a united effort to save the remaining survivors and destroy the self-aware machine network in San Francisco. Now, more than ever, protecting the sixteen-year-old version of Sergeant Kyle Reese becomes the war's priority; however, things are further complicated by the arrival of the enigmatic human with the pale memories of death row, Marcus Wright. More and more, as Skynet deploys an army of relentless machines to terminate John and Kyle, humankind's salvation lies in the hands of a single rescue team. Is all hope lost?—Nick Riganas
