As with the other Terminator films, a protagonist and antagonist are sent back to the modern-day from a dark future using a time-travel device. The protagonist (Mackenzie Davis) is a technologically augmented human super-soldier named Grace, who lands in Mexico City in order to try to act as a savior for humanity in the future (Natalia Reyes). The antagonist (Gabriel Luna) is an ultra-powerful Terminator model called a Rev-9, whose mission it is to terminate a young female autoworker living in Mexico named Dani Ramos. Lending assistance to the resistance is the return of Sarah Connor (Linda Hamilton), who sees kinship in Dani because she has been thrust into the same position as key to humans surviving the A.I. onslaught of the future. Arnold Schwarzenegger makes an appearance in the second half of the film as a T-800 model Terminator named "Carl" who has assimilated into human society after completing his mission of taking out John Connor. Tim Miller directs.
