When a beautiful young woman returns to her hometown, she is horrified to discover her estranged father on the run for a string of grisly murders. But as the manhunt intensifies and the local sheriff becomes the next victim, it’s clear the killer is something other than human. Resurrected from the depths, intent on vengeance, this unstoppable force of nature has risen to destroy and devour the entire town, limb by limb.
