At the point when John Connor (Jason Clarke), pioneer of the human resistance against Skynet, sends Kyle Reese (Jai Courtney) back to 1984 to ensure his mom, Sarah (Emilia Clarke), from an Eliminator professional killer, a startling unforeseen development makes a modified course of events. Rather than a frightened server, Sarah is a gifted warrior and has an Eliminator watchman (Arnold Schwarzenegger) close by. Confronted with impossible associates and risky new foes, Reese sets out on a surprising new mission: reset what's to come.
