Directed by Isaac Gabaeff, The Sand (aka Blood Sand) follows a group of friends who are having a big beach party. As the party begins all the teenagers agree to put their mobile phones in the trunk of a car in an effort to ensure that no one will post compromising pictures or videos online. One girl though, Heather (Etalvia Cashin) keeps her phone and videos the party. As the party progresses Vance (Hector David Jr.) and Gilbert (Cleo Berry), find a large ball covered in a strange gooey substance. Surely it couldn’t be dangerous?
When the morning after finally hits we discover that Kaylee (Brooke Butler) and Mitch (Mitchel Musso) have woken up on the lifeguard shack. Kaylee’s boyfriend, Jonah (Dean Geyer) wakes up in a car next to a girl named Chanda (Meagan Holder). In the back seat are Vance and his girlfriend, Ronnie (Cynthia Murell).
Meanwhile, Gilbert wakes up, stuck from the waist down in a trash barrel, having been put there as a prank after passing out whilst Marsha (Nikki Leigh) wakes up, topless, having fallen asleep on top of a picnic table. The rest of the teenagers, including Heather, are nowhere to be found; there are, instead, a bunch of empty sleeping bags in their places.
Marsha accuses Heather of having stolen her top; she leaves the picnic table to find her. Kaylee, having witnessed a bird getting sucked into the sand tries to warn her, but Marsha doesn’t listen. She is immediately immobilized in the sand and is visibly discombobulated when she gets trapped. Vance attempts to help her but he, too, becomes trapped when he touches the sand. Vance and Marsha are swallowed by the creature, as their bodies sink into the sand, much to the horror of their friends. Jonah sees the cracked ball from the night before and concludes that it must have been an egg, and whatever hatched from it has burrowed under the sand and has wiped out everyone!
