Gulf Coast Bigfoot Research Organization (GCBRO) founders Bobby Hamilton and Jim Lansdale lead a team of commandos on a mission to find and kill a Bigfoot in order to prove its existence to science and protect the public from a future attack.
The GCBRO investigates a frightening Bigfoot encounter on a family's large farm in the swampy Sabine River area. The hunters have a run-in with their old teammate-turned-rival Dr. Webb Sentell, a neuropsychologist and Bigfoot no-kill advocate.
The GCBRO responds to possible sightings of a dead Bigfoot and terrifying devil-monkeys. Controversy erupts over whether to kill or not at a Bigfoot gathering, and the crew have an exciting chase through the forest at night.
