An old woman named Murph addresses the camera and says her father was a farmer like almost
everybody else was at the time but he did not start off this way
Her father Cooper was a pilot, as we see him in a craft of his own
We also see Murph as a child going into Cooper's room, asking him if he was dreaming about
a crash Murph thinks there is a ghost in the house,
which Cooper doesn't believe in We see clips of elderly people talking about
the area they lived in, which was made up of crops and cornfields
Cooper also lives with his 15-year-old son Tom and father-in-law Donald
Murph brings in a piece of Cooper's craft to the table during breakfast
Cooper drives the kids to school to drop them off
but also to meet with Murph's teacher He lets Murph handle the truck, and they end
up getting a flat tire on the road Tom teases Murph and calls her "Murphy's Law"
Cooper gets out to change the tire when a drone flies overhead
He hops back in the truck and drives through the cornfield to chase after it
They follow it toward the edge of a hill near a lake
Cooper then gets out a device that controls the drone, which he lets Murph try out
Cooper meets with the kids' school principal and Murph's teacher Mrs. Kelly
The principal shows Cooper Tom's test grades and says he'll make a great farmer, though
Cooper says Tom could make a great engineer, even if the results don't seem to suggest
this Mrs. Kelly shows Cooper a textbook that Murph
brought in to show the other kids This federal textbook is forbidden in the
school since they use textbooks that say the Apollo missions were faked to
bankrupt the Soviets Cooper isn't happy with what his daughter
is being taught and he mentions that if his wife hadn't passed
away, she would be there and would be calmer about this
Murph ends up getting suspended Cooper is called home to find a bunch of tractors
around the crops There appears to be something wrong with the
food supply The next day, the family goes to a baseball
game Donald complains that they serve popcorn at
the place instead of hot dogs The crowd then sees that a huge dust storm
is happening Cooper drives the family home with protective
masks Murph realizes the window in her room is open,
so she and Cooper run upstairs to shut it On the floor are thick and thin parallel lines
across the floor made out of the dust Cooper analyzes them and determines they are
coordinates Cooper drives to the facility that the coordinates
lead to, with Murph stowing away in the truck He gets out bolt cutters to go through the
fence, only for a robot TARS, to show up and apprehend Cooper
Cooper is interrogated by TARS until Dr. Amelia Brand comes in
She brings Cooper to a room with other scientists, with Murph sitting among them
Leading the group is Amelia's father, Professor Brand, along with fellow scientists Doyle
and Romilly They identify themselves as being part of
NASA Professor Brand explains the situation, which
is that the Earth's crops and food supply are slowly dying off
and the planned mission is to find a new home in the universe to sustain human life, as
there may be no hope to save the planet Several astronauts before them, led by the
famed Dr. Mann, went on what is called the Lazarus Missions prior to the rest of the
group to find a new world Romilly explains that a wormhole has been
discovered that can lead them to a new galaxy with a
chance to explore a new world for human life This is their Plan A
Plan B would involve rebuilding life through fertilized embryos that would replace a human
life Cooper disagrees with this plan, so he agrees
to Plan A Murph is not happy with him and she storms
up to her room when they get home Cooper tries to comfort Murph in her room,
but she is too angry to listen She says that she deciphered a message from
the books falling off her shelf in Morse code that says, "Stay"
Cooper promises to return home, though he doesn't know when
He gives Murph his watch but she throws it against her bookshelf
Before Cooper leaves, a couple of books fall off the shelf
Cooper drives to the station in his truck as Donald and Tom see him off
Murph is too late to say goodbye Cooper looks in the passenger seat in the
hope that Murph possibly stowed away again but she is not there
and His eyes fill up with tears Cooper, Amelia, Doyle, and Romilly blast off
into space to begin their mission to Mars and then Saturn, along with TARS and the ship's
computer CASE They dock their shuttle onto the space module
Endurance Romilly and Doyle put themselves in hypersleep
Back on Earth, Professor Brand brings Cooper's truck back for Tom to use
He also tells Donald and Murph that they can send messages that will be transmitted to
Cooper, but Murph is still mad The astronauts soar through the wormhole,
passing through the cosmos and stars and infinite space
They know that time passes differently for them on these planets due to the different
gravitational pull One hour out there amounts to bout seven years
on Earth Taking that into account, Cooper knows that
it's crucial that they find a way to complete the mission
without wasting what could be a decade for the people on Earth
He makes a plan to go around the black hole Gargantua
to what he and the others refer to as "Miller's planet"
The team lands on Miller's planet, which is set upon a seemingly endless body of water
Romilly stays in the craft while Cooper, Amelia, Doyle, and TARS set out
They find a wrecked beacon in the water belonging to Miller whose body is nowhere
to be found From the distance, Amelia thinks she sees
mountains when it is actually a colossal wave headed toward them
Amelia tries to salvage the beacon as Cooper orders her to return to the craft
Doyle is killed by a wave of water while the others make it back inside
There, Romilly has aged 23 years Amelia realizes that Miller was probably there
hours ago and died minutes before they got to the planet
There is also a number of video messages in the craft that were sent to Cooper
Most of them are from Tom It starts with Tom in his current age saying
that he misses his dad and that he's met a girl named Lois
The messages then show Tom as an adult He has married Lois and they have a baby named
Jesse Cooper is overwhelmed with emotion and he
starts crying Another video message shows Tom looking forlorn,
as something has happened to Jesse He also mentions that Donald has passed away
The last message is from a now adult Murph She is at the age when Cooper left and promised
to return She starts to weep, making Cooper even more
emotional Presently, Murph is working with Brand at
NASA to finish the equation which he's been working on that would figure
out how humans can escape Earth's gravitational pull
She still harbors some resentment toward her father for leaving her
Cooper, Amelia, and Romilly are sitting together trying to figure out which planet they should
head to next, Edmunds or Mann From their discussion, Cooper learns that
Amelia is in love with a fellow scientist named Wolf Edmunds, for whom one of the planets
is named She hopes to be able to see him again soon,
and she states that love is the one thing that transcends time and space
Murph goes to the hospital where her partner Getty directs her to Brand's room
He is dying When Murph expresses hope for the mission's
success, Brand admits that he solved his equation long ago
but was missing data from a singularity behind a black hole for it to be complete, so he
puts what little faith he has left in Plan B
With his dying breaths, he crushes Murph's hope
After he passes, Murph sends a video message to Amelia to inform her of her father's death
The astronauts come across an icy planet with frozen clouds
There is another craft on the surface with a pod inside
Another person is in hypersleep - Dr. Mann. He awakens and sees Cooper, and he gets overwhelmed
to see another human again, bringing him to cry in Cooper's arms
Afterward, Mann explains the environment of the planet to the team, stating there are
67 hours in the day and another 67 at night, as well as the icy conditions
The team then receives Murph's message to Amelia, which also addresses Cooper
Murph asks if both Cooper and Amelia knew that the mission was a sham and that Cooper
simply abandoned his family Amelia is just as shocked to hear this, and
Mann admits that he has considered the mission to be a failure
Amelia begins to cry Murph has dinner at the old family home where
Tom lives with his family He and Lois have another son named Coop
Coop and Lois suffer from a cough that is attributed to the conditions of the area
Tom seems to be ignoring the problem and refuses to take his family out of there
Cooper and Mann go out to navigate the planet together while Romilly and Amelia stay behind
Here, Mann turns on Cooper and removes his emergency oxygen pack before pushing him over
the edge of a hill It's revealed that he forged data of the viability
of the planet so he could be found and saved Since he has considered Plan A a failure,
Mann opts for Plan B, and knowing that nobody can survive on this
planet, he leaves Cooper to die Cooper fights back, only for Mann to crack
Cooper's visor by slamming his head against it
Mann escapes while Cooper tries to contact Amelia for help
Mann ends up killing Romilly by blowing up his station while Amelia rushes to Cooper's
aid They pick up TARS and fly after Mann
Getty tries to help Coop with his cough, but Tom doesn't want his or Murph's help, and
he punches Getty in the face He and Murph leave, following other vans that
are evacuating the area as another dust storm starts forming
Murph then drives into the cornfields and douses it with gas before lighting it up with
a flare to persuade Tom and his family to leave
Cooper and Amelia find Mann trying to dock his shuttle with Endurance in space
but he cannot as he hasn't secured the airlock Amelia tries to warn him that the shuttle
will depressurize, but it is too late and causing an explosion that kills Mann
Cooper manages to get Endurance back under control with the help of TARS
He and Amelia then plan to use the robot to gather data on the singularity behind Gargantua
and then chart a course to Edmunds' planet Knowing that they have a limited energy and
oxygen supply with them Cooper and Amelia try to make it home carefully
However, Cooper separates himself from Amelia to let her go on without him
Cooper ends up falling through what looks like another wormhole
it puts him in an odd dimension of sorts He hears the voice of TARS speaking to him
Cooper floats against what looks like a wall He peeks through it and sees Murph as a child
He is looking at her through her bookcase Cooper calls out to her and starts pushing
the books TARS explains that he has stumbled upon a
new dimension relative to time, space, gravity and that the beings that invented this dimension
led Cooper to find this place They know humans couldn't have created this
just yet, but soon enough Cooper sees himself on the day that he left
Murph, and he yells at himself to stay He notices the watch he left Murph sitting
on the bookshelf and he taps his fingers against the lining
of the dimension to try and communicate with Adult Murph through the
hands on the watch Adult Murph is still trying to get Tom's family
out of the house while the fire in the cornfields is being extinguished
Now, both Cooper and Murph realize that Cooper was the "ghost" in Murph's room
and he was the one that left the message in Morse code for Murph that read, "Stay"
Adult Murph then figures out that her father is communicating with her
This gives her what she needs to solve Brand's equation and to save mankind
She goes to the research facility, gathers all the papers she once worked on and throws
them into the air before excitedly kissing Getty
Cooper, meanwhile, falls through the dimension and drifts through space before blacking out
Cooper awakens in a medical station The doctor tells him to relax and take it
slow as he is now 124 years old
Cooper walks to the window and sees kids playing baseball when the batter hits the ball and
it goes through the window of a house a house that is directly above the playing
field The doctor says they are in Cooper Station
over Saturn Cooper thinks it's named after him, but it's
named after Murph The doctor says she'll be arriving in a few
weeks Cooper is given the remains of TARS and is
brought to his old home He works on him and reprograms his settings,
making him more honest and slightly more humorous Cooper gathers with his great-grandchildren
at the hospital to be reunited with Old Murph as she lay in bed surrounded by her family
She is happy to see her father, who has fulfilled his promise to return to her
Knowing that her time is short, she encourages Cooper to continue living and sharing his
life with someone She tells him to find Amelia, who is lost
and setting up camp somewhere out there Amelia is shown on Edmunds' planet putting
Plan B into effect trying to rebuild a community with the smaller
organisms and unaware of what has happened with humanity
Cooper decides to follow Murph's advice and seek out Amelia himself
