one day oceanographer Tom's Family his wife Julia and two children Cassie and Ben set off on a yacht trip in the Caribbean Sea while Tom and Ben are busy fishing and Cassie is absorbed in her Gadget Julia goes for a swim suddenly something unsettles her Julia looks around but the sea remains as calm as ever however she feels a distinct sense of dread as though something large and dangerous is circling around at the same time the instruments on the yacht start acting strangely but Tom preoccupied with fishing pays no attention to them meanwhile Julia feels
worse and eventually begins to drown she screams but the family doesn't hear her the water seems to shift and pull her farther from the yacht as the situation becomes critical Tom finally hears her voice he rushes to the helm and the yacht moves toward the distant Julia Tom dives into the water with the children's help they pull her aboard and revive her Tom is angry as he always asks that swimmers notify the others when going into the water Julia apologizes and the incident is soon for gotten besides the family has a reason to celebrate today
is their son Ben's 13th birthday Tom Lights the candles on the cake and everyone congratulates Ben who receives gifts while Cassie takes a group photo of the happy family at that moment Cassie's boyfriend calls her he asks her about the swim but suddenly a sudden and intense storm begins in the background Cassie is worried but her boyfriend reassures her that he's safe the connection cuts off Cassie tells her parents about the storm on land but then everyone feels some jolts rushes to the deck and sees massive whale carcasses surfacing around the yacht Tom explains that
sometimes whales get disoriented during storms but these animals are pushing the yacht threatening their safety Tom dives into the water and soon returns aboard injured while trying to figure out what's going on he cut himself on the propeller Julia stitches up the cut on her husband's shoulder and he explains that the yacht's shafts seem bent likely from a tail strike now they're unlikely to be able to sail away later Cassie tries to reestablish communication but there's no signal the radio isn't picking up any signals either Tom begins calculating their supplies there's enough water for about
4 days no more but they were on a shipping route so someone is bound to find them however ominous sounds come from outside and when the family steps out onto the deck they see glowing objects falling from the sky they fall closer and closer and Tom taking a risk starts the engine he manages to steer the yacht away from the next meteorite but the engine is finally damaged the next object falls so close that the family can see they are artificial satellites of Earth a strong wind starts blowing and the instruments go Haywire the terrified
family hides inside the yacht which is being tossed by the waves they put on life jackets and prepare for the worst when a strange ringing sound is heard causing nose beds in nausea Tom tries to signal for help with a flare gun but it's all in vain the family barely survives the night in the morning they were relieved to find themselves alive but there's a gaping hole in the side of the yacht and it's unclear why there's still afloat the family goes outside and freezes in amazement the water is gone and their boat is standing
on a rocky outcrop in the middle of a Stony desert where the ocean once was sometime later Tom tries to reassure his family saying that not everyone could have perished he takes measurements and realizes that the compass is lying North isn't where it's supposed to be this means the Earth's poles have shifted such a thing has happened on Earth before but a long time ago it turns out that the sea has retreated to where the land used to be and most likely Humanity has perished Cassie can't bear this Revelation and runs to the cabin asking
to be left alone Julia goes to inventory the remaining supplies while Ben releases a bunch of colorful balloons into the sky hoping survivors will come to their aid meanwhile Tom turns on the radio sending out distress signals unexpectedly he hears a response it's from natto the captain of a small submersible they were deep underw water when the catastrophe happened and that's why they survived however all communication systems have failed and expecting help is feudal according to his calculations the sea will return in about a week and it will be harsh so the man advises them
to find Higher Ground and stay there Julia orders the children to pack their things Tom directly asks the captain if he can save their children nuto explains that the submersible is very small unfortunately Naruto's partner died and he can only take one person after some persuasion Tom convinces Nao to take both children and he provides his coordinates Tom charts a course on the nautical map and Promises to reach the location in a couple of days the next morning the family is almost ready to embark on their Journey Tom steps onto the deck and suddenly sees
a man with a dog approaching he walks toward him and greets him but notices that the man is injured he offers the traveler some water the man drinks it and then suddenly punches Tom in the face which Julia sees she rushes to her husband as the traveler plunges a makeshift spe into Tom's chest the dog keeps Juliet Bay though she freezes in horror herself realizing there's no saving her husband she runs to the yacht the man pursues her injuring her arm nevertheless Julia climbs onto the deck and the children hearing her screams run to her
Aid together they barricade the doors to the cabin after that Julia hides Cassie and Ben in a locker giving her daughter the flare gun and instructing her to shoot only as a last resort meanwhile the killer tries to break down the doors and eventually succeeds Julia hides in the back bathroom patching up her wound entering the Intruder heads straight to the galley and grabs some food it's clear that he's very hungry holding a can of food the man begins searching the yacht while Julia arms herself with a kitchen knife he enters the cabin but the
woman jumps overboard hiding beneath the yacht the killer peers through the hole but doesn't see her however the dog attacks Julia forcing her to kill it the man hears the Yelp goes outside and finds the dog's body meanwhile Julia climbs back onto the yacht through the port Hool on the opposite side she falls straight into the Killer's hands he beats her throws her onto a couch and grabs her throat intending to strangle her Cassie Witnesses all this and realizes it's the last resort she opens the locker and Fires at the man the shot throws him
to the side but the flare sets the yacht on fire Julia orders the children to flee while she sneaks into the galley the killer only injured tries to attack again Julia kicks him away grabs the packed bags and jumps overboard where Ben finds his father's body Cassie runs to the corpse and sobs over it Julia kisses her deceased husband but seeing the killer leap from the burning yacht she takes the children and leaves the boat explodes behind them the family runs across the Stony desert and soon takes shelter in a rocky Canyon where a stream
flows however the water is salty and undrinkable Cassie shares a small amount of water with her brother but he refuses to drink the boy feels guilty believing the killer came because he saw the balloons Cassie also voices this thought but Julia orders her to stop and defends her son explaining that he didn't mean any harm she tells the children to gather themselves as a long journey awaits and then she spots the killer again still relentlessly following their Trail the family hurries onward that evening Ben finds the carcass of a hammerhead shark and tries to butcher
it but Julia sees the pursuer and orders the children to run they soon come across a field of once flooded toxic waste barrels but Julia urges the children forward despite the threat of contamination knowing the Killer is still on their heels the family walks along the former ocean floor weaving through piles of plastic and other trash dumped by humans soon Julia notices that Ben is severely dehydrated and gives him the last drops of water Cassie has a breakdown convinced that they have no chance of survival but Julia commands them to keep moving eventually they find
the fuselage of a plane that crashed into the sea long ago and crawl inside to rest Julia examines the last photo of their family and recounts the story of her first meeting with Tom which happened at her hospital where Tom was brought with decompression sickness after a failed dive the children weep remembering their father and saying their final goodbyes to him at night Cassie is awakened by a noise and steps outside to sit near the plane out of the darkness the killer approaches her unaware that the girl is acting as bait as he prepares to
grab her Julia ambushes him stabbing the man with a knife at dawn the family prepares to continue their Journey Only to discover the Killer's body body has been scavenged a sign that something even more dangerous than humans lurks in the desert they move on Julia consults the map when Ben suddenly rushes ahead his mother yells for him to stop but the boy Sprints toward a salty puddle and manages to drink a few gulps Julia drags him away but the boy becomes sick soon they come across some plastic chairs and build a makeshift Shelter From the
Sun resting inside it suddenly Julia hears strange sounds she steps outside and sees something that forces her to wake the the children realizing the new danger they begin running soon they spot a large ship in the distance surrounded by crashed containers in a few wandering people Julia calls out to them but they seeing thousands of giant crabs Dash into a container and lock the doors ignoring her please for help the three climb onto a container though the crabs managed to wound Julia in the leg nevertheless Julia Cassie and Ben sit on top watching the crabs
penetrate through a crack in the doors killing everyone inside despite the people's attempts to fend them off Julia ties a scarf around her leg and passes out the next morning she wakes up alone terrified and calls for the children but it turns out the crabs have moved on and the children had gone down to search for food and weapons Julia cauterizes her wound while Ben examines the found weapons searching through the containers they find a small amount of food and water in the pocket of one of the deceased Julia finds a radio and contacts natto
he responds explaining that he was also attacked by Deep Sea arthropods based on his observ ations the sea will return soon which is why the creatures have emerged Julia begs him to save her children but she's unsure where to go because she's lost the map nto fires a flare Ben sees the direction and the family rushes toward it soon they see a yellow submarine in the distance but reaching it is difficult due to the terrain of the former seabed Cassie dislikes her mother's talk about saving the children but Julia refuses to answer and pushes the
family onward they are forced to pass through a canyon contaminated with toxic waste at one point they are caught in a rock slide and Julia becomes separated from the children she orders them to continue and when Cassie refuses Julia pleads with her to save her brother Cassie and Ben make it out of the canyon and reach the submarine but inside there's no one suddenly natto badly wounded emerges from behind the boat he admits that he has no chance of surviving and orders them to climb aboard but Cassie goes back for her mother who is fending
off the emerging crabs her bull bullets nearly depleted Cassie climbs the rock barrier and extends her hand to her mother they managed to reach the submarine just as the crabs overrun nto who dies in their claws the family climbs aboard and just then an ocean wave crests Over the Horizon the water lifts the submarine and drags it across the rocks and as Julia watches everything that happened over the past few days Flash before her eyes she passes out when she awakens she finds the vessel at a standstill Julia opens the hatch and the family emerges
