A group of friends are having a party at the beach with some of their classmates because it’s spring break. While one of the friends Heather (Etalvia Cashin) is filming the party, two of the boys named Vance (Hector David Jr.) and Gilbert (Cleo Berry) find a giant ball covered in a strange gooey substance. The party continues, with all party guests having to put their phones in a bag so the party can’t be seen online.
The next morning, two of the friends, Kaylee (Brooke Butler) and Mitch (Mitchel Musso) awake on the lifeguard building. Kaylee’s boyfriend Jonah (Dean Geyer) awakens in a nearby car next to a girl named Chanda (Meagan Holder). In the back of the car are Vance, and his girlfriend Ronnie (Cynthia Murell). Gilbert wakes up, having been stuck in a trashcan and a topless girl named Marsha (Nikki Leigh) wakes up, having fallen asleep on a table. The rest of the teenagers, including Heather, are nowhere to be found, just a bunch of empty sleeping bags left in their place.
Kaylee sees a bird get sucked into the sand. Marsha, who thinks Heather has stolen her top, goes to find her. Kaylee warns Marsha not to touch the sand but she does so anyway. Marsha becomes visibly distressed when she can’t move, so Vance goes to help her but he finds that he can’t move when touches the sand either. Both Vance and Marsha are gruesomely killed as their bodies sink into the sand, much to the horror of their friends. Jonah sees the cracked egg on the edge of the beach and concludes that whatever hatched from it has burrowed under the sand and killed everyone, including Vance, Heather and Marsha.
