Grad student Devin Toulson is writing his dream thesis on Myths in American History, but when his research takes him on a journey reaching back centuries, Devin finds something horrifying. Something that crosses cultures, locations, and eras. Something that returns for a bloody feeding every 23 years. Will this young man's investigation uncover simply an urban legend or will he come face to face with an immortal monster that has terrorized humanity from the shadows since man first walked the country?
