There are creatures both legendary and unidentified roaming the Appalachian Mountains, and a band of hard-core hunters and trappers have made it their life's work to investigate them. For generations, supposed sightings of these monsters -- with such names as Wolfman, Devil Dog, Wampus Beast, Mothman and Lizard Demon -- have occurred along the 1,500-mile stretch of mountains, and it wasn't until the members of the Appalachian Investigators of Mysterious Sightings had their own personal encounters with these creatures that they became believers. Now, the AIMS crew, led by founders "Trapper" John Tice, Jeff Headlee and Willy McQuillian, use both traditional techniques and modern technology to track, trap and capture these monsters. Maybe AIMS will snag its first one while cameras are filming "Mountain Monsters"!
