Directed by David R. Ellis (Snakes on a Plane and The Final Destination), this shark-infested fright flick bites into the action right away. Sara (Sarah Paxton) invites six of her college friends for a weekend vacation at her lake family's lake house. Prepping for a weekend of fun and partying, the gang first finds trouble as soon as they hit town.
After running into some locals, trouble begins brewing. Sara is able to squash the ensuing brawl as she quickly recognizes that her old boyfriend Dennis (Chris Carmack) is part of the pack. She is able to smooth things over so that they can carry on with their weekend, although it is clear that Dennis is none too thrilled to see her with a new beau Nick (Dustin Milligan).
It isn't long after that the group realizes that the redneck locals aren't their worst fear. It takes no time at all for the kids to realize that there is a shark in lake, a shark that just took off with Malik's (Sinqua Walls) arm. With Malik injured, as the group calls for help they start to realize how isolated they are with no cell phone reception, and no boat to get to the other side of the lake. As they begin making desperate attempts to save themselves they learn that there is not just one shark in the lake. There are fifteen deadly species of sharks in the lake, and to make matters worse they were put in the lake on purpose. Lake-goers are lured into the lake as bait by psychos that are filming the attacks for website footage.
Seeking refuge with local law enforcement (in the form of Sara's chip-on-the-shoulder high school boyfriend Dennis) she and Nick readily climb on board his boat in an attempt to get to safety. Matters worsen from there as their final flee to safety proves to hold more danger than just the sharks.
Hang onto your seat, sharks plus 3D cause a few jumps!
