The Sand, also titled Killer Beach, is a 2015 American horror film directed by Isaac Gabaeff and starring Brooke Butler, Meagan Holder and Mitchel Musso. At least one version of the opening credits reads "Killer Beach", but the closing credits give the movie title as "The Sand."

A large group of friends - including Kaylee, Gilbert, Ronnie, Jonah, Chanda, Mitch, Vance, Marsha, and Heather - are having a party on the beach, leaving their mobile phones in the trunk of a car in an effort to ensure that no one will post compromising pictures or videos online. Vance and Gilbert find a large ball covered in a strange gooey substance and bring it to the rest of their friends.

The next morning, Kaylee and Mitch wake up in the lifeguard shack. Jonah, who is Kaylee's estranged boyfriend, awakens in a convertible next to Chanda, having had sex with her the previous night, along with Vance and his girlfriend, Ronnie. Gilbert wakes up stuck from the waist down in a waste container. Marsha awakens topless on a picnic table. The rest of the teens - those who had fallen asleep directly on the sand, including Heather - are nowhere to be found.

Kaylee witnesses a bird suddenly getting sucked into the sand and tries to warn Marsha, who goes to search for Heather, but Marsha does not listen, and her feet get stuck in the sand. Vance rushes to help her, but trips and falls face-first into the sand; the skin on his face melts off. His and Marsha's bodies are pulled beneath the ground by an unseen force. Kaylee discovers that thin tendrils, barely visible, emerge from the beach and reach towards her hand when she holds it close to the sand. Jonah sees the ball from last night, now cracked in half, and concludes that it is a large egg and that whatever hatched from it has burrowed under the sand.

Unable to access their phones as they are locked in the trunk of the car, the group experiments to determine the creature's reach. Jonah uses two surfboards as a bridge to reach a picnic table. In the process, the creature moves the boards causing him to slip, and slashes his stomach, leaving a painful wound that starts seeping pus. He notes that the creature avoids the ashes of the previous night's bonfire, indicating that it hates fire. While attempting to retrieve their phones, Ronnie crushes her fingers under the trunk's lid.

A beach patrol officer arrives. They implore him to help them, but he dismisses them, believing them to be under the influence of drugs. He walks across the sand unharmed, protected by his boots, but is killed by the creature after dropping his keys and attempting to retrieve them. Kaylee manages to retrieve his pepper spray. Mitch attempts to get to the car with his feet wrapped in towels and covered in pepper spray, but falls onto the sand and is killed.

Kaylee jumps to the car and helps free Ronnie's fingers, then together with Chanda, reach the picnic table where Jonah is injured. While doing so, Kaylee confronts Chanda about her affair with Jonah; Chanda admits she did it out of jealousy. Gilbert cuts his stomach on the edge of the trash barrel. The scent of blood from both Ronnie and Gilbert's injuries attracts the creature, and Ronnie is pulled under the sand when trying to get to the table. Chanda uses Mitch's idea to run across the sand to the truck with pepper-sprayed towels on her feet. The creature, having grown much larger tentacles, pulls Gilbert beneath the sand and knocks Chanda unconscious.

At night, Chanda finds a self-inflatable raft in the truck, which she, Kaylee, and Jonah use to reach the patrolman's car. The ground erupts and a huge glowing tentacle assaults Kaylee. She finds two gas cans on the rear rack and uses them to set one of the tentacles ablaze. The trio lock themselves in the car. Once the tentacles stop, Kaylee and Chanda discover that Jonah has died from his injuries, and begin to cry over the loss of their friends.
