After choosing two more intriguing cases to investigate, Bill, Austin and Chi Lan travel to Chopaka Lake, WA, to investigate a compelling video that many claim is solid proof of a Bigfoot in the remote area. With many experts saying that no human could make such a dash across rugged terrain, Austin is put against the clock to put that theory to the test. Later, with Bill overhead in a spotter plane with a thermal imager, Austin and Chi Lan find themselves surrounded by mysterious heat sources. Meanwhile in upstate Washington, Ben, Jael and Larry take on a case that has divided the paranormal community for over ten years - the staggering case of Dr. Reed and the woodland Alien attack. Using their special effects skills to the maximum, the team try to recreate the infamous video, before Ben puts his FBI training to the test in a one on one interrogation of the elusive Dr. Reed.
