Interstellar

In 2067, life on Earth is collapsing. NASA scientists, Amelia Brand, Romilly and Doyle, are set to embark on an intergalactic mission to find life on other planets, after earlier missions - called Lazarus - reported habitable environments in faraway systems, accessible by a wormhole near Saturn. Former NASA pilot, Cooper, is led by coincidence (Cooper refuses to term it 'supernatural') to the secret NASA facility, where Amelia's father and mission leader, John Brand, convinces him to join.

Despite objections from his teenage-daughter Murph, Cooper leaves to pilot the Endurance spacecraft. After a two-year voyage to Saturn, the spacecraft passes through the wormhole, emerging into a planetary system orbiting a supermassive blackhole, Gargantua. Three planets, previously explored by Miller, Mann and Edmunds respectively, have shown signs of habitability. The first and closest, Miller's planet, turns out to be an ocean-world with massive tidal waves. Doyle perishes on the planet, and Amelia and Cooper struggle to escape. They return to the Endurance after 23 Earth-years have passed - the extreme time dilation caused by the planet's proximity to Gargantua's gravity. Alone aboard the Endurance, Romilly significanty ages.

Their full mission compromised, the team decides to investigate Mann's planet, at the expense of ever visiting Edmunds. While there, message is relayed from Earth that Brand has passed away. On his deathbed, Brand told Murph, herself a scientist now, that the Endurance mission was never meant to return (since humanity's Earth-existence is doomed). Murph feels betrayed that Cooper left knowingly, though he was misled as well. Cooper resolves to return, but Mann tries to stop him. It emerges that Mann falsified data of his planet's habitability, in hopes of being rescued. While he escapes, Romilly is killed in the process. Mann himself dies in space, leaving Amelia and Cooper as the lone survivors.

Aboard a damaged spacecraft with limited resources, Cooper proposes a gravitational slingshot around Gargantua to Edmunds' planet. This will save fuel but lose them time (50+ Earth-years) due to dilation. At the last moment, Cooper ejects from the Endurance, sacrificing himself so that Amelia can complete the mission. Cooper is sucked into the blackhole, falling into an unusual tesseract, where time is a physical dimension. He sees himself decades ago inside Murph's bedroom and realises he can interact with objects there. Knowing Murph will return in her adult life, he encodes data about the blackhole into the ticking of his old wristwatch (placed on Murph's bookshelf). After Brand's death, Murph visits her childhood bedroom, where she comes across Cooper's wristwatch. She deduces that the supernatural coincidence that led Cooper to NASA was Cooper himself (communicating from the future), and uses the wristwatch-data to finish Brand's incomplete work.

Cooper is ejected from the tesseract and is picked up in the future (his present) by a spacecraft orbiting Saturn. He is reunited with Murph, who directed humanity's exodus from a dying Earth. Murph, now older than Cooper (nearly 120 years old), does not want him to experience her death. She suggests he seek out Amelia on Edmunds' planet. As Cooper sets out again, Amelia is shown adapting to life on the alien planet. Edmunds has died, and robots build a colony on the planet's surface, as Amelia removes her helmet to breathe in the air from the planet's atmosphere.
