Part 4/12:
The story centers around Jack Harper, played by Tom Cruise, and his assistant Vika, tasked with maintaining giant water-collecting drones called Harvesters that supply fuel to the new colony. Their mission is to extract water from Earth's oceans and ensure the survival of humanity elsewhere. Once the mission ends, they are to board the last evacuation ship leaving Earth. However, Jack begins experiencing haunting dreams of a life before the war—memories that shouldn't exist, given that both he and Vika have undergone memory wiping.
