Sharkansas Women's Prison Massacre

When a fracking mishap accidentally rips apart the earth's crust, the resulting hole opens up a gaping underground waterway to a vast and mysterious 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 intended victims in a small deserted cabin in the heart of the wetlands. Death may be the only means of escape!
