Scream of the Banshee

An archeology professor unwittingly releases a creature that is able to kill with the power of its bone-splitting scream. A mysterious box and map lead her to an ancient relic that unleashes a banshee, a wicked spirit that haunts and slays those who hear its piercing screech. With the help of her students and a disgraced internet prophet, she must find a way to stop the legendary creature before it's too late.
