Earth’s crops are often lost due to climate change and blight. Cooper, who was once an engineer and space shuttle pilot of the National Aeronautics and Space Administration, is forced to become a farmer to help solve the food crisis. Cooper's 10-year-old daughter Murphydiscovered that the books on the shelf in her room fell to the ground for no reason, thinking it was a ghost phenomenon. Soon after, a sandstorm left binary coordinates in Murphy's room. After the two drove to the coordinates, they discovered that it was the North American Air Defense Command.
The head of the base, Professor Brandrevealed to Cooper that there was a wormhole near Saturn. He believed that extraterrestrial wisdom intended to assist humans to migrate to distant galaxies. The General Administration had sent twelve people about ten years ago. Scientists traversed the wormhole and landed on multiple planets that are considered to be habitable. The data sent back show that one of the planetary systems centered on the black hole "" has three planets that may be suitable for colonization. Planetary scientists named to landing: Miller, Edmondsand Mann. Cooper agreed to Professor Brand’s request and acted as the pilot of the spacecraftto perform the: Plan A confirmed the habitability of the planet through Professor Brand The gravitational equation assists the humans on the earth to colonize; Plan B is to colonize with multiple human embryos, and the humans who remain on the earth will be extinct. Murphy was deeply angry because he was worried that Cooper would not return. Cooper left without saying goodbye. He and Professor Brand's daughter Emilia, Physics The scientist Romili, the geologist Doyleand the two robotsand Case Go to space to board the Perpetual and set off.
Everyone arrived at Miller Star first; the gravitational time expansion caused by the huge gravitational force of "Kagantuya" made Miller Star approximately seven years old for one hour. But everyone missed that the data received from Miller in the past few years was actually only a few hours ago on this planet. Therefore, except for Romily and Tas, all members took the airshipafter they landed on the planet. , It was discovered that there was only a vast ocean on the surface and huge tsunamis frequently appeared. The tsunamis struck Doyle and delayed his return journey. After returning to Perpetual, they found that it had been more than 23 years for Romiley.
Everyone thought that so far they could only choose to go to one of the remaining two planets, and after some arguments, they finally decided to go to Mann Star. At the same time, Murphy has grown to be the same age as Cooper when he left the earth. She joined NASA to assist Professor Brand in solving the gravity equation needed to save the earth. The Philippine admits that Plan A is just a lie and cannot be realized. On the other hand, the scientist Mannwas awakened from artificial sleep and said that the equation could not be completed due to the lack of data on the gravitational singularity of the black hole. Therefore, the real purpose of Perpetuality is not to save the earth. Cooper was so angry and regretful that he planned to abandon the project and return to Earth to find his family. In a later camp search mission, Mann destroyed Cooper's space mask and stated that all the livable data were fake data created by him, hoping that the National Aeronautics and Space Administration could send someone to rescue him. After Mann left Cooper to die, he captured the Rover and headed to Perpetual. At the same time, Romiley tried to obtain detection data from the robot Kippdismantled by Mann , triggering a trap and exploding. Emilia rescued Cooper, who was about to suffocate from inhaling too much ammonia, and the two chased Mann in a landing boat. Mann opened the airlock when the docking with Perpetual was not completely successful. The loss of control and decompression caused him to die and caused the Perpetual to spin out of control. Cooper successfully docked the Perpetual to stabilize it.
The resources on the Perpetual were not enough to return to Earth, so the two sailed to "Kagantuya", shot Tas to let it collect data on the gravitational singularity, and after receiving the data and sending it back to Earth, it uses gravity to help it go to Edd. Mons Star implements Plan B. In order to reduce the quality of Perpetual and allow Emilia to escape, Cooper asked the rover he was driving to separate and enter the black hole after running out of fuel. However, after the rover was destroyed and ejected and escaped, Cooper found himself in A non-linear flow of the fifth-dimensional tesseract; Cooper now understands that humans who have transcended time and space and evolved to a higher civilization have created four-dimensional tesseracts and wormholes to save humans in the past, and he also understands that he is also Murphy. The ghost I met at the time, guided myself to participate in the Lazarus project. Cooper transmitted the black hole data obtained by Tass to her through Murphy's watch through gravitational waves; when the adult Murphy recalled this incident, she finally found out the message of her father. She completed Professor Brand's equation and allowed humans to leave. Earth, go to live in the space station orbiting Saturn.
The four-dimensional tesseract space was closed after the data transmission was completed, and Cooper was sent away from the wormhole and returned to the vicinity of Saturn, where he was rescued by the Saturn space colony personnel. At this time, he has been away from the earth for 91 years, theoretically 124 years old. Cooper reunited with the dying old Murphy on the space station, but Murphy did not want his father to witness his death and let him go, and persuaded him to go to Edmonds to find Emilia. Cooper and Tas travel to Edmonds on a next-generation rover.
