In 1998, three years after averting the threat of Skynet, Sarah and John Connor are enjoying life by a beach in Livingston, Guatemala, when they are suddenly attacked by a T-800 Terminator. Sent back through time by Skynet prior to its erasure, the Terminator murders John before leaving. Twenty-two years later, an advanced Terminator, called Rev-9, is sent back in time to Mexico City, to murder Daniella ‘Dani’ Ramos, who will become a threat to the machines in the future. A cybernetically enhanced soldier, Grace, is sent from 2042 to protect her. The Rev-9, disguised as Dani’s father, infiltrates the automobile assembly plant where Dani and her brother Diego work, but is thwarted by Grace, who escapes with the siblings. The Rev-9, revealing its ability to split into its cybernetic endoskeleton and shape-shifting liquid metal exterior, pursues them, killing Diego and cornering Grace and Dani. However, Sarah arrives and temporarily disables the Terminator with explosives.
