Synopsis: When a fracking mishap accidently rips apart the earth's crust, the resulting hole opens up a gaping underground waterway leading to a vast and mysterious subterranean ocean somewhere deep below. Instantly, giant prehistoric sharks begin wending their way upward toward a murky bog in the heart of the Arkansas bayou. Unfortunately for a group of female prisoners on a work detail in the swamp, the deadly sharks attack without warning - pinning a hapless group of potential victims in a small deserted cabin in the heart of the wetlands. For these wayward women, death may be the only means of escape!
