Billy McGregor just wants to enjoy his summer before high school, but a creature lurks within his lake and seems to be picking off the residents one at a time. As a horror-buff, he’s quick to pick up on this and with nobody else seeming to notice, it’s up to him and his friends to take matters into their own hands. But they aren’t the only ones after the creature. A local cop realizes the several deaths are linked and an organization called SID is trying to cover it up. They have their own plans for the creature, but if they don't capture it quickly, things could spiral out of control due to a potential for infection. A single bite or scratch will turn any person it injures into another one of its kind. It’s a race for who can deal with the creature first, but will any of them be successful against a genetically engineered killing machine?
