Set in a future where a failing Earth puts humanity on the brink of extinction, it sees an intrepid team of NASA scientists, engineers and pilots attempt to find a new habitable planet, via interstellar travel.
Summaries. When Earth becomes uninhabitable in the future, a farmer and ex-NASA pilot, Joseph Cooper, is tasked to pilot a spacecraft, along with a team of researchers, to find a new planet for humans.
What were they trying to figure out in Interstellar?
Interstellar is about Earth's last chance to find a habitable planet before a lack of resources causes the human race to go extinct. The film's protagonist is Cooper (Matthew McConaughey), a former NASA pilot who is tasked with leading a mission through a wormhole to find a habitable planet in another galaxy.

Interstellar plot
When Earth becomes uninhabitable and humanity faces extinction, farmer and ex-NASA pilot Joseph Cooper (Matthew McConaughey) pilots a ship of scientists and engineers through a wormhole to find a new habitable planet in another galaxy.
It turns out that NASA has secretly been planning an interstellar mission to try and find a new home for humanity, and Cooper's just the man for the job. But, here's the problem. Because of the severe time dilation, Cooper will experience mid-mission; by the time he gets home, it'll be decades later.
Interstellar is a movie surrounding an idea about the future Earth which will become uninhabitable due to a widespread crop blight and a second Dust Bowl.
Who are the 5th dimensional beings in Interstellar?
The fifth-dimensional beings are not aliens; the fifth-dimensional beings are humans from the far, far, far future, who have evolved beyond the limits of the third dimension. These far future humans are now helping to create themselves by giving humanity the wormhole to a new galaxy.
TARS relays the quantum data to Cooper in Morse code. Cooper in turn relays the quantum data to Murph, in Morse code, through the hands of a wrist watch. Murph somehow knows it's her father relaying quantum data to her through the watch.
Mann takes Cooper around the planet, things seeming perfectly normal till he suddenly attacks Cooper, revealing that he faked all the data he sent to NASA, and that he and Dr. Brand always knew saving humanity was impossible and colonisation was the only way forward.
It is then revealed that he and Professor Brand knew that Plan A was impossible and that the only contingency that allowed for human continuity was Plan B. Mann did not want Cooper to return to Earth with the Endurance, as he now needed it to reach Edmunds' planet with the remaining crew to start a colony.
Cooper traveled for 2 years to the wormhole and subsequently lost 23 years in gravitational time dilation on Miller's planet. When he returns to the Endurance he receives Murph's message that she is now the same age as Cooper when he departed.
It took the spaceship 18 months to travel to the wormhole, then 23 years passed from exploring planet Miller. Murph said (cried) in the video to his dad that she is finally the same age as him when he left. Which tells us that she and her dad are both 35 years old toward the end of the movie.
The goodbye scene between Cooper and young Murph (early on in the movie when he decides to take on the mission) is emotionally excruciating. She begs him to stay but then refuses to speak to him when it is revealed he doesn't know when he will return.
Towards the third act of the film, Cooper comes to the speculative conclusion that the wormhole was placed there by future humans in order to ensure the survival of their species, and giving them access to the quantum-data required to complete Professor Brands equation of gravity, further granting them the ability to ...
When Murph burnt a section of his crop to distract him while she rescued his family to cure them, he returned to the farm where Murph exclaimed that she had found their father and that she could save the world.
Originally Answered: Who is “they” in Interstellar? During the tesseract scene, Cooper (Mcconaghey) implies that “they” are actually just humans from the distant future who have evolved to the point that they can experience the universe in 4 dimensions, and can communicate across time.
He ended up in the hospital bed because he went unconscious when the Tesseract was closing, and the 5th Dimensional beings transported him out of the black hole and assisted him through the Saturn wormhole. He was then found by rangers from cooper-station, and was taken into medical care.
On his deathbed, Professor Brand confesses to Murph that he lied about his Plan A's prospects – that he failed to “reconcile relativity to quantum mechanics” and his gravity project needs much more data. She takes on the project herself and beams out the bad news to space, where Coop and Amelia receive it.
While fans may continue to hope for an Interstellar 2, the absence of concrete plans or release dates suggests that the future of the franchise is uncertain.
First half of 2086: "Coop" is born. Around June 28, 2092: Cooper and Brand along with CASE return to Endurance to find Romilly, who reports that 23 years had passed since they left for Miller's planet. Murph works with Professor Brand at NASA. Cooper catches up on a cache of 23 years worth of video messages.
Mann needed the Endurance to survive and complete Plan-B with the surviving crew. Meanwhile, Romilly successfully accessed KIPP's archives, which revealed the true data of Dr. Mann's planet. Before Romilly could inform the others, the robot detonates, killing him in an explosion.
Once he passes through the event horizon, he enters a tesseract, which is a construct that gives him access to a fifth dimension. This is where every moment in time exists all at once. For Cooper, it is physically represented by Murph's bookshelf, through which he can see her childhood bedroom.
