This one is a bad bigfoot movie by the same guy who incredibly, directed The Town that Dreaded Sundown, Charles B. Pierce.
Dr. Lockhart is a University of Arkansas crypto zoologist, on the hunt for the legendary beast.
Lockhart recruits the help of two of his students, Tim and Tanya, as well as Tanya’s friend Leslie, none of whom have any experience in anthropology, zoology or any related discipline. Good help is hard to find.
The group heads to the eponymous Boggy Creek, and set-up camp in the woods with a pop-up trailer, and secure their perimeter with a SONAR system.
They keep an eye out for the elusive beast, while the doc relates to the group tales he had heard centered around the creature, presented in flash backs.
