These days in Mexico City. Dani Ramos, 21, works on an assembly line in an automobile plant. Her life is turned upside down when she suddenly finds herself confronted with two strangers: on one side Gabriel, a highly evolved, indestructible and protean Terminator machine, a “Rev-9”, coming from the future to kill her; on the other side Grace, a genetically enhanced super-soldier, sent to protect her. In a breathless chase through the city, Dani and Grace owe their salvation to the dreaded Sarah Connor, who, with the help of a mysterious source, has been tracking the Terminators for decades. Determined to join this unknown ally in Texas, they set out on their journey, but the Terminator Rev-9 is relentlessly pursuing them, along with police, drones and border patrols. The stakes are all the higher because saving Dani is saving the future of mankind.
