the movie begins in Iraq with planes bombing an area miles and his team American soldiers take cover in a crumbling building while shooting at the enemy sadly their Captain is shot in the neck and dies in miles's arms an explosion shakes the building and a bright light appears miles rushes out to fight again but is hid in the stomach and Falls he sees two missil likee objects fly by followed by a strange aircraft that shines a light on him making him scream before passing out later miles wakes up in pain in a room with no
windows or doors is just gray panels he tries to stand and listen through the wall but his wound bleeds and he falls again he cries for help asking if he's in a hospital but no one answers using his emergency supplies he cleans and wraps his wound miles tries His Radio but it doesn't work he sees the word abandon written upside down on the wall which wasn't there before he calls for help again in Arabic looking again the wall now says Abandon All and the floor reads save thy Sinner's Soul feeling dizzy miles takes off his
backpack and close as the room heats up the phrase on the wall changes to abandon all hope miles sweats heavily and starts to panic hitting the wall and begging to be let out his sweat boils on the ground and he begins to wonder if he is dead slowly losing his mind like a caged animal desperate he grabs his gun and starts shooting at the walls eventually the heat becomes unbearable and Miles Falls screaming in pain before passing out when he wakes the temperature is normal he grabs his flask for water but the room starts spinning
throwing him and his belongings around after a few minutes the spinning stops and he notices the room has changed some things are stuck to the ceiling he tries the radio again and Hears A woman's voice but the call ends quickly he remembers his cell phone on the ceiling and using binoculars carves the number on the floor with his knife the phone rings and Miles tries to reach it worsening his wound he throws a shoe but it also gets stuck on the ceiling Frost appears on the walls so he puts on clothes and curls into a
fetal position moments later the frost vanishes leaving him with purple fingers he hears the phone ring again an alarm rings and the room moves causing the phone to fall despite being thrown around miles grabs the phone before the spinning stops he regains access to his helmet and takes out a picture of his wife and daughter checking the call log he dials the number and hears a woman who explains she's been kidnapped and is in a spinning room miles confirms she's in a room like his and notices a faint glow on his arm realizing they might
be the light sources he asked the woman questions but she gets scared thinking he's part of a scam he yells explaining he's trapped in bleeding too she apolog izes and they agree to work together she introduces herself as damy and explains she was on the highway before being kidnapped miles recalls his team was near the highway damy asks if he was stationed there making miles uneasy because he never mentioned being a soldier damy reassures him saying she guessed based on his questions and way of speaking suddenly damy stops speaking and grunts in pain mil dog
tags are yanked back and the chain chokes him an invisible force pulls his arms open causing him to drop the phone his body floats a bright light appears stretching his limbs before dropping him to the ground on the phone miles hears damy being dropped too a strange noise follows and Miles warns damy the room is about to move again instead of spinning the walls move inward miles panics tries to push a wall but Falls and passes out when miles wakes up he discovers the room has shrunk he has a panic attack as damsey calls saying
her room has shrunk too she uses soft words to calm him down then curses as she sets her shoulder back in place miles notices words on the wall in different languages and damy confirms they are in her room too she explains she wasn't physically grabbed when she was on the highway and mentions a location in Massachusetts this makes miles realize it doesn't make sense for them to be communicating as his phone is on a closed Network and he thinks they're in Iraq damy freaks out saying setting this up would take many days yet she claims
she's only been there for about an hour she saw the same strange things in the sky as miles before being taken miles shouts through the walls to see if damy is next to him but she can't hear him he wonders how she got his number and damsey says it appeared on her ceiling suddenly the phone announces another call Miles tells damsey to call back later and takes the new call a man speaking broken English says they can't win because they can't solve the equation and must die before miles can ask for clarification the call ends
and the phone switches back to damy Disturbed miles numbly starts talking to her she asks where he thinks the signals are coming from Miles asks if she knows about an equation on the wall but damsey can't see any equation she becomes suspicious again seeking reassurance that they are in this together damsey wants to find a pattern to understand why they were chosen as she can't believe it was random miles changing his bandages says there is no pattern she shares that she's an algebra teacher engaged to a former Soldier miles notices she doesn't sound happy talking
about her fiance implying he changed after returning from war miles admits he and his wife aren't on good terms he eats his last rations while watching the words on the walls some have years ranging from 1951 to 2007 miles thinks they are being messed with point out that 2007 is in the future damsey is confused and asks what year it is and he says it's 1991 damy laughs sarcastically asking if he's using a walkie-talkie he says it's a satellite phone she mentions social media and selfies but miles doesn't understand suddenly the room glows and emits
a noise that makes miles's ears bleed he writes the times on his arm before grabbing his head screaming in pain and passing out moments later miles wakes up trembling and struggling to breathe he forces himself to answer the ringing phone when the word answer appears on the wall he tells damy there's not enough air and realizes the room is even smaller now damy is experiencing the same thing she asked him to draw something on the wall and Miles makes an a which damy surrounds with a handprint in her time it's 2020 she theorizes that she
miles and others are in the same room at different times miles starts feeling dizzy and babbling nonsense before collapsing he asks damy about the future and is saddened to hear the war is still ongoing he calls it the the sins of the father and shares that his dad fought in Vietnam before passing out damy calls his name and he wakes up saying she needs him he notices his Arabic dictionary has fallen out and some symbols match those on the wall he translates the message writing it on the floor for damy to see the result is
an equation indicating that a mathematician among the kidna left it as a clue they realize all the kidnapped people are connected to math suddenly someone scribbles over the equation so Miles quickly writes it on his arm damy confesses she has an advanced degree in math but works as a teacher because her fiance doesn't like it when she talks smart she asks if the war has changed him and made him hurt someone he loves miles defensively tells her she wouldn't understand how War transforms people he shares that his dad used to beat his mom damsey remembers
the equation and Miles urges her to write it on the wall before another change happens she struggles using her keys to scratch the wall suddenly the room starts shaking and miles's hands are forced to the ground the gravitational pull increases pulling his knees down and extracting the bullet from his wound he bleeds more as his face hits the ground miles screams in pain but after a few minutes it's over miles reaches for the phone and curses when he sees the cracked screen the alarm rings and the room starts spinning again since it's smaller miles can
jump from wall to wall instead of being thrown around the spinning doesn't last long this time and the light goes out for a few seconds when it returns he notices the room has shrunk even more miles tries the phone at first nothing happens and he's ready to give up but eventually someone answers the person keeps repeating phrases like they can't see or know and fail sacrifice which miles doesn't understand so he hangs up now he can talk to damy again damsey says she broke her arm that she's running out of battery and that death is
their only option miles realizes she's been working with the foreign man the entire time and scolds her for the Betrayal damy finally shares what she knows they were caught by a superior species testing human intelligence to see if they're a threat damy thinks Humanity isn't smart enough to go against these aliens then they started discussing how they can use the equation to control the room damy thinks about the equation and how the solution might be the key to escaping miles then asked what if only one person might escape the person who solved the equation first
suddenly the light turned off in the darkness miles can be heard screaming and cursing at the aliens ignoring damy's attempts to calm him down suddenly he starts having flashbacks from the war and memories of his dad beating his mom causing him to yell in psychological torment eventually the flashback stop and Miles tells the aliens they have won asking them to end things crying he prepares his gun feeling he can't deal with his trauma anymore he questions his dad for killing his mom and admits he feels like he's becoming his father but doesn't want to be
after reminding himself that he isn't his father miles lowers the gun and calls damy who is also crying she saw flashbacks of her fiance and admits she has scars from all the times he beat her one day she finally ran away driving so fast down the highway that she crashed that's when the aliens took her damy asked miles if he ever heard his wife miles answers that he never did but has thought about it disgusted damy insulted him and hung up then a call comes from the foreign man scolding miles for trying to solve the
equation he insists they mustn't win because humans will become a threat as bad as the aliens he warns that the aliens shouldn't see Earth as a threat or who knows how they could react suddenly the alarm rings and the room starts shrinking again miles tries to stop it but soon his body is Twisted in a very tight space at that moment damy calls again and asks the same question miles swears he never hit his family admitting he had urges but fought against them to avoid being like his dad miles thinks he's sick and believes damy
should be the one to solve the equation he apologizes for who he is and for what damy went through and damy forgives him miles asks her to find his family and tell them he loves them and that they deserve better now motivated damsey uses the time between room movements to finish the equation the answer is one so she tries concentrating on taking control of the room and spinning at one time but nothing happens thinking it over damy realizes that one person alone can't be a threat the answer signifies mankind is one the aliens want to
see if humans are capable of dropping the fighting and working together miles concentrates and starts pushing the room to help damy they scream together until the room suddenly explodes into a bright light to their shock damy and Miles see each other touching hands and floating in the light the wall panels float around them showing all the other kidnap people this means they've solved the equation and freed all the victims damy and Miles say hi to each other and share a smile before disappearing into the light miles reappears in Iraq he gets up and tries to
talk to his team but there's no answer he starts making his way back to his team only to hear sirens wailing and see planes flying by when he finds the American troops they're looking at something dangerous in the sky the movie concludes with Miles staring at the sky leaving what he sees unrevealed to the audience
