Sharks attack a fish rodeo on the Mississippi River, and it is up to a group of locals to stop them.
Right under everyone's noses, a school of aggressive sharks finds its way to the broad Mississippi River, and before long, they attack a slow riverboat, snapping off the unsuspecting tourists' heads. However, with the famous annual fish rodeo just around the corner, the local authorities are not willing to let a few rogue sharks get in the way of having fun--and of course, making a few extra bucks. What they don't understand is that now that the underwater invaders have tasted succulent human flesh, they'll stop at nothing to get more. Now it's up to an old familiar face, along with a team of locals, to help try to fend off the blood-thirsty aquatic assailants before they all become shark bait. Can they stop the ferocious Mississippi River Sharks?—Nick Riganas
A shark winds up on the deck of a riverboat in New Orleans, killing several people. Meanwhile, young college student Tara Mitchell has just returned to her hometown next to the Mississippi River in order to participate in an upcoming fish rodeo with her father, and local shop owner Ray. Actor Jason London, star of the popular "Shark Bite" film series, is appearing as a special guest at the rodeo. News reporter Allison Harding, and her cameraman Phil arrive to cover the event. The town's mayor Bill "Big Bill" Braddock is informed of the riverboat attack in the meantime, although is more concerned with the rodeo activities than the attack. Meanwhile, a woman named Mrs. Chapman is killed by a shark while painting next to the river.
When the fish rodeo begins, Ray is forced to return to the store in order to collect a shipment, leaving Tara at the dock. Tara soon meets up with her old friends Wyatt, who is a big fan of Jason London, and the Shark Bite films, and Eric, whom she has had a secret crush on since high school. Ray, in the meantime, witnesses a fisherman being eaten by a shark, and calls Tara to warn her. Tara, and Eric set out to find Ray, only to come across Jason, and Big Bill looking at the severed head of Mrs. Chapman. Big Bill soon confesses to Tara that there are sharks in the river, and sends Jason to warn people of the sharks, although nobody believes him. Ray, meanwhile, gets the attention of the town sheriff, and he's attacked while inspecting the fisherman's body, although Ray manages to scare it off. Allison, and Phil then arrive, although Phil is quickly eaten while inspecting the body.
Tara, and Eric reunite with Wyatt, who pulls a shark out of the water using a winch on the back of his truck. Jason arrives with a machete, which Tara uses to kill the shark. However, it soon becomes apparent that there's more than one shark in the river, and after they fail to shut down the competition, Tara, Eric, and Wyatt decide to enter it in order to kill the sharks, although they are required to enter their phone numbers onto an entry sheet in order to qualify. Big Bill's assistant retrieves them while Tara, Eric, and Wyatt go back to the marina, although he drops them into the river, and is eaten while trying to retrieve them. Tara, Eric, and Wyatt go to collect supplies from Ray's shop, and Wyatt asks Jason to help, although he refuses to do so, much to Wyatt's disappointment. As Tara, Eric, and Wyatt prepare to leave, Jason is eaten by a shark.
Tara, Eric, and Wyatt arrive at Ray's shop, and collect weapons, and supplies. Meanwhile, the sheriff, Ray, and Allison begin heading towards the marina, although encounter a man being devoured by a shark on the road. They kill the shark before the fisherman walks away unharmed, although they're left stranded on the road, and begin walking to the marina as a result. The sheriff finds a fisherman stranded in the water with a shark surrounding him. The shark rams the boat, causing the fisherman to accidentally shoot an arrow, which kills the sheriff. Meanwhile, Tara, Eric, and Wyatt arrive back at the river with guns, and bombs, where Big Bill confronts them, and confiscates their bombs. They then devise a plan to capture the sharks by hanging a net over a bridge, lure the sharks into the net, and then lift them up using Wyatt's winch. In the meantime, Big Bill discovers fisherman Possum attempting to steal the prize trophy. When they fight over the trophy, one of the sharks jumps up eats their arms before they both fall into the water, and are devoured by the sharks.
While setting up the trap, Tara, and Eric begin confessing their love for each other, only to be interrupted by Wyatt, who sends Tara to get a net. Eric asks Tara out on a date after they kill the sharks, to which she accepts. The group then finishes setting up the trap, and Ray, and Allison arrive at the marina shortly after. As Tara, Eric, Wyatt, and Ray begin the process of trapping the sharks, Allison records the event on her camera. The group then manages to trap the shark, and they begin raising the net. Wyatt then attempts to blow up the dangling net with a pipe bomb, although the bomb detonates too late, and falls into the water, where it explodes. The sharks then begin falling back into the water, pulling the truck in with it, although Wyatt manages to drive the truck forward, pulling the net up onto the bridge, where a truck runs over the sharks, finally killing them. Ray starts a relationship with Allison, and Tara, and Eric share a kiss. Wyatt finds the prize trophy under the bridge, although a decapitated shark head then falls on him.
Three months later, Tara, and Eric have officially become a couple, and Wyatt is helping Ray running the store, although is wearing an eye patch due to the injury sustained from the shark head falling on him. As Tara, Eric, and Ray leave, Wyatt sees another shark movie starring Jason's twin Jeremy on TV before a girl who's lost in town comes into the store, and the two talking about their love of the Shark Bite films as the film ends.
