It is 2077. The Earth has been mostly devastated by a battle with aliens in 2017. But humanity was being relocated to Titan, the largest moon of Saturn. Most of the land is to be avoided, because of radiation. But there is an area safe for human life, and a small team, an "effective team" of two people monitor the automated drones and the big machines that are harvesting energy from the ocean.
Tom Cruise is Jack, and Andrea Riseborough is Vika,and they make up the team. Most of their memories have been wiped, they live in a futuristic apartment high in the sky, and Jack uses a flying contraption to do his job.
We never actually see Melissa Leo, only her image on a monitor as she talks with Jack, but she is only known as "Sally", with an exaggerated southern drawl, and she seems to be the person in charge of monitoring Jack and Vika, the drones, and the energy-harvesting machines.
Let's just leave it at this, not everything is as it appears to be and, when a type of spaceship crashes in the area, Jack finds 5 people in suspended animation pods, apparently from the year 2017. Solving this new riddle is the subject of the rest of the story.
This is science fiction, it can raise any number of questions, but if you just go with what you see, it is very nice entertainment.
SPOILERS: Jack was in fact one of the astronauts from 2017, and one of the people he recovered from the pods was his real wife, Olga Kurylenko as Julia. Then Jack apparently encounters his own self, and eventually finds out there are many of him, as clones. Sally most likely is not a real person, but only an image, and there is no colony on Titan, there is no dangerous area of radiation, it is all a misdirection to get humans to keep harvesting the Earth for the aliens. Jack gets aligned with a group of other human survivors, lead by Morgan Freeman's character, and they devise a plan to travel to the alien command center and with nuclear explosives destroy them. But Jack has to sacrifice himself. Mission accomplished, his wife Julia is seen in a bucolic setting with young child, and a Jack clone walks up. The child calls him daddy, they will be a family anyway.
