Synopsis:

Fisherman Matthew Boyd (Richard Dreyfuss) is fishing in Lake Victoria, AZ when a small earthquake hits, splitting the lake floor and causing a whirlpool. Boyd falls in and is ripped apart by a school of prehistoric piranhas that emerge from the chasm and ascend the vortex.

Jake Forester (Steven R. McQueen) is admiring attractive tourists in Lake Victoria as Spring Break begins. He reunites with his old crush, Kelly (Jessica Szohr), before being chased off by her boyfriend. He meets Derrick Jones (Jerry O'Connell) an eccentric pornographer, and Danni (Kelly Brook), one of his actresses. Derrick convinces Jake to show him the hot spots on the beach for an upcoming pornographic film the following day.

Meanwhile, Jake's mother, Sheriff Julie Forester (Elisabeth Shue), searches for the missing Matthew Boyd at night with Deputy Fallon (Ving Rhames), who has found Boyd's boat. They find his mutilated body and contemplate closing the beach down. The next morning, a lone cliff diver is attacked and consumed by the marauding fish.

Eager to enjoy spring break for once, Jake bribes his younger sister and brother, Laura (Brooklynn Proulx) and Zane (Sage Ryan), to stay home alone so that he can show Derrick around the beach with Danni; eager to be left alone unsupervised, they agree for a share of his payment. Zane, however, becomes impatient at his unsuccessful dock fishing--attributing it to the activity on the lake--and drafts Laura to go fishing on a small sandbar island. They forget to tie the boat down and are stranded in the middle of the lake.

Jake goes to meet with Derrick but encounters Kelly first, who invites herself onto Derrick’s boat, The Barracuda. Jake meets Crystal (Riley Steele), another of Derrick’s actresses, and cameraman Drew (Paul Scheer). They film an underwater love scene between Danni and Crystal before partying.

Alerted by the quake, a team of seismologist divers--Novak (Adam Scott) and his two partners, Sam (Ricardo Chavira) and Paula (Dina Meyer)--arrive and are escorted to the fissure by Julie; Novak speculates that the rift is a passage to a prehistoric lake buried underneath Lake Victoria. Paula and Sam scuba dive to the bottom, discovering a large cavern at the mouth of the opening, containing large egg stalks. Sam is torn apart by a massive school of piranha when he ignites a flare; Paula scrambles to escape but is pursued to the chasm and eaten to the bone. Novak and Julie pull her corpse into the boat, capturing a lone piranha still attached. Novak and Julie take it to the pet shop owner, Mr. Goodman (Christopher Lloyd), who examines the fish and explains that the piranha are a long-extinct prehistoric species, and had been trapped in the underground lake for over two million years.

Jake spots Laura and Zane on the island, and forces Derrick to rescue them; an increasingly agitated Derrick inadvertently causes the boat's propeller to get stuck in seaweed.

Julie, Novak, and Fallon try to evacuate the beach, but their warnings are ignored until the entire school of piranhas attack the tourists. Novak boards a jet-ski with a shotgun to help while Fallon ushers people to shore and Julie tries to get swimmers into the police boat. A floating stage set up in the water collapses from the weight of all the panicking guests and the wet T-shirt contest host (Eli Roth) is killed.

Meanwhile, Derrick manages to break free of the seaweed, but then crashes into some rocks, breaking the glass observation dome and flooding the rooms below deck. Kelly is trapped in in the kitchen while Derrick, Crystal, and Drew are thrown from the boat. Crystal and Drew are devoured while Danni manages to get a partially eaten Derrick back on board. Jake, panicking that he can't reach Kelly, calls Julie.

After saving many tourists, Julie and Novak commandeer a boat and take it to the sinking Barracuda. Fallon stays behind fighting off the piranhas with a shotgun in shallow water. Seizing the motor off a speedboat, he turns it on and shreds much of the swarming school with it, sacrificing himself but giving more swimmers a chance to get out of the water.

Julie and Novak reach Jake and attach a rope to his boat. Julie agrees to come back for Kelly after the kids are safe. Danni goes over the rope first but the piranhas latch onto her hair and pull her off the line and into the water killing her. Laura, Zane, and Julie make it to safety but Jake breaks the rope. Using Derrick's corpse as both distraction and bait, Jake ties the line to himself and goes underwater to save Kelly. He ties Kelly to him and lights a flare after releasing the gas in a pair of stored propane tanks. Novak guns the boat away just as the piranhas surround Kelly and Jake. They are dragged to safety and the propane tanks explode, destroying the boat and the ensuing shockwave killing most of the piranha.

Mr. Goodman calls Julie on the radio, telling her that the glands on the piranha they obtained were not mature, meaning that the piranhas they've been fighting are babies. Novak questions aloud what an adult piranha would look like. The answer is revealed when a piranha the size of a large dog launches itself out of the water and kills him. (wikipedia)
