Due to the threat of the invasive species, Park Ranger Terry O’Hara (Tiffany) issues permits to the local hunters to exterminate the pythons – much to Nikki’s dismay. However, the hunters themselves – including Terry’s fiancé Justin (Carey Van Dyke) – are quickly eliminated by the giant snakes.

Meanwhile, Nikki and her group set up cameras all over the Everglades to monitor Terry’s activities. They catch and record Terry and Angie feeding the steroid-laced chickens to the alligators.

Two guys on dirt bikes are riding on the beach, but are then attacked by a predator in the sand. Meanwhile Jimmy Green (Corin Nemic) the son of the Mayor (Edgar Allan Poe IV) of the small island town of White Sands returns home to throw a party. At the same time the local sheriff John Stone (Eric Scott Woods) is investigating the deaths of the men from earlier believing it to be a murder. Years prior to the events John's wife and child along with 13 other people were murdered in a shark fling at a party Jimmy threw and doesn't believe they are dealing with it again. John's sister, Deputy Brenda Stone (Vanessa Evigan), contacts a shark expert against her brothers wishes. A couple is devoured by a sand shark and on the other side of the beach as Jimmy is preparing for a layout with Willie (Delpaneaux Wills), Erin (Hilary Cruz) and Amanda Gore (Gina Holden) is confronted by John and Brenda (the latter had a previous fling with Jimmy and is not happy to see him). Just then a couple having fun on the beach are both attacked by a sand shark causing panic. At a town meaning the locals can't afford to have the beaches closed as the town is already in a financial crisis. A man named Angus McSorely (Robert Pike Daniel) tells them they are dealing with actual sand sharks that can swim through sand and offers to take care of them for the town but is written off as crazy. Sandy Powers (Brooke Hogan), the shark expert Brenda called, was watching the meeting and has a talk with John while examining a shark tooth. At night two men are being stalked by a sand shark while on their raft in the water they tried to escape but the shark got them on land. Fearing his party may be cancelled Jimmy calls someone to bring an already dead shark but because the tooth found does not match the dead shark the beached stayed closed. After a power outage caused by the shark Brenda arrests Jimmy and we learn of their relationship from before the film's events. They spot John on the beach with three guys at gun point as one of them brought a fake shark to fool him into keeping the beaches open. After seeing a dorsal fin moving in the sand they all realize the old man was right. Sparky (Jack Kennedy) who brought the fake shark does not hear the others telling him to get off the sand as he was trying to get the power back on and is killed by the shark who ultimately dies after chopping on the electrical cable causing it to explode and turn to glass. With the threat gone the beaches are reopen and the party is back on. However the tooth found earlier is only a baby tooth and Sandy believes the dead shark's mother is out there looking for its baby. With the party underway it is revealed there are more sand sharks as both Amanda and Willie are killed by one. More sand sharks appear and start killing the party goers and Brenda is also killed trying to get people off the beach. John and Sandy are stuck on rocks where the sharks can't get to them and the sharks attack the docks with few casualties as Angus shows up to get people out of there. With the ferry not showing up for another day Jimmy, John, Angus and Sandy take one final stand against the sand sharks using Jimmy's speakers, napalm and Angus' homemade flamethrower. Unfortunately the music stops and Jimmy goes to fix the speakers but the wire is torn and the sand sharks swarm Jimmy who sacrifices himself so the sharks stay in one place as Angus encases them all in glass. With the sand sharks now encased in glass the threat appears to be gone, but a large dorsal fin can be seen moving in the sand in the cliff above. The mother of the sand sharks bursts through the side and eats Angus. Trapped in Angus' hut John and Sandy make one last effort to kill the mother by tossing a flamethrower full of napalm into her mouth as they escape the hut the flamethrower explodes in the sharks mouth destroyer and the hut at the same time. Back at the trailer where Erin was hiding after a shark killed Willie in front of her is talking to someone who wants to throw a beach party is killed by the same shark who ate Willie as it was waiting for her the entire time hinting that the threat is not over.
