Bigfoot: The Lost Coast Tapes follows the story of Sean Reynolds, a highly acclaimed investigative journalist who strongly believed in paranormal phenomena. However, his career took a hit when the most watched episode of his reality show, focused on paranormal phenomena, was revealed to be a hoax.
One day, Sean comes across a news report about a "Bigfoot Hunter" named Carl Drybeck, who claims to have the body of a dead Sasquatch. Sean is convinced that Drybeck is a fraud and decides to create a new show exposing people's paranormal claims as hoaxes.
Sean gathers his old film crew and travels to Northern California's "Lost Coast" to meet with and interview Drybeck. He is determined to prove that Drybeck's claim is a hoax, risking his comeback, his life, and the lives of his documentary film crew in the process.
