An amusement park paleontologist and a hapless security guard team up to stop an invisible raptor from wreaking havoc on their small town.

After a top-secret experiment goes wrong, a hyper-intelligent invisible raptor escapes the lab and begins wreaking havoc in the surrounding neighborhood. When the creature's identity is uncovered, it soon becomes clear that a disgraced paleontologist-alongside his ex-girlfriend, an unhinged amusement park security guard, and a local celebrity chicken farmer-is the town's only hope for surviving the raptor's ravenous rampage.
