Plot
The film opens with a man named Day, who is lying in a drained pool with several injuries to his body. He looks down and screams as an alligator bites down on his leg.

Six days earlier, Day is working on a photoshoot in the same pool, which is full of water. His girlfriend Koy and his dog Lucky wait for him to finish.

The following morning, Day clears the pool of the props used for the photoshoot and relaxes on an inflatable raft, with Lucky tied to a leash nearby. Day is advised by his boss that the pool is being drained, so he will need to get out soon. Day ends up falling asleep, and by the time he wakes up, the water level is too low for him to get out. He attempts to climb out, only to severely injure the nail of his right index finger. He screams for help, but no one is around to hear him.

The next day, while Day is asleep on the raft, Koi shows up to surprise him. Not noticing the lowered water level, she jumps into the pool before Day can warn her, but she slips and hits her head on the diving board. Day pulls her onto the raft and tends to her while she is unconscious. That night an alligator appears and crawls towards Lucky but slips on some metal pipes by the side of the pool and falls in.

By the morning, the water has completely drained, and the couple are alone in the pool with nothing but a sofa left over from the shoot. Day bandages Koi's wound with duct tape that he takes from the sleeping alligator's mouth. He uses Koy's necklace to unscrew the pool's drain cover to find an exit, but the alligator climbs in ahead of him. Day braves the drain tunnels and finds a small pumping station where a ladder leads to a locked grate on the surface above the pool. He makes it back to the pool just in time to prevent the alligator attacking Koi. Koi wakes up and it is revealed that she is pregnant.

The next morning, Day loses consciousness as result of the heat, hunger, and the lack of his diabetes medication. He wakes later that night, and Koi informs him that the alligator has laid several eggs inside the pool with them. They manage to trap the alligator in the drain and proceed to start a fire, which enables them to cook and eat the eggs.

Tension starts to arise between the two as they try and fail to escape from the pool, and after Day admits to feeling he would not be a good father, and to wanting Koi to have an abortion. Koi berates him and inspires him to prove his worth by saving them.

On the fifth day the couple release the alligator back into the pool and enter the drain system themselves. They manage to open the grate a few inches and Day salvages an insulin shot, which was accidentally dropped into the grate a few days earlier.

Seeing what he believes is a drone, Day leaves Koi in the pumping station and makes his way back to the pool, only to discover it's a remote-controlled glider. He notices a line of barbed wire has been blown over and he attempts to climb it but falls and breaks his leg. He fashions a splint from pieces wood and duct tape and falls unconscious. He later wakes with severely lacerated hands, and with the alligator chewing his broken leg in the image we saw in the opening scene. Day manages to beat the animal away with a bucket.

That night it rains heavily, and the pumping station starts to fill with water with Koi inside. Day evades the alligator and makes it back into the drain tunnels, but this time goes the opposite way to the pumping station. He finds a grate, which he manages to open, but emerges in an adjacent pool, also empty. Distraught and weak, he crawls back into the drain tunnel and falls asleep.

On the morning of the seventh day, two men arrive after their remote-controlled glider gets stuck at the bottom of the empty pool. They fix a bamboo ladder to a pile of concrete pipes and climb down. Once in the pool, they notice blood stains and the word 'help' written in duct tape, but decide to leave anyway.

Awoken by their talking, Day makes his way toward the ladder but is attacked by the alligator. He fends off the animal, but the concrete pipes slip in the heavy rain and the ladder is completely retracted. With the rainwater now dangerously high in the pumping station and the alligator attacking once more, Day collapses in defeat. The alligator bites his torso and is about to bite his head when Koi blows a whistle through the grate just as the rainwater submerges her entirely. The sound makes Lucky jump into the pool, but as he is tethered, he hangs himself on his leash. Day impales the alligator's mouth with the leg of the sofa, and kills her with a metal pipe. He uses Lucky's body and leash to climb out of the pool and prys open the grate to the pumping station, rescuing Koi before she drowns.
