PIRANHA 3D
Plot:
"The fictional Lake Victoria is the caldera of a prehistoric volcano. Each 4th of July weekend, the population of Lake Victoria, Arizona swells from 5,000 to 50,000 as young people flood the town to celebrate. When tremors tear open a crack in the lake floor, millions of prehistoric piranha are released. The ravenous fish unleash havoc on the unsuspecting party-goers."

The movie Piranha 3D is gonna be a bloody feast! I thought sharks were scary, well, now I understand Piranhas would be a much bigger threat!
