Teresa "Trenny" Gibson vanished from Clingman's Dome in the Smoky Mountains in 1976 while on a school field trip. One minute she was there...and then she was never seen again. Only one teacher was on the trip to supervise, and the kids, their parents, and the school didn't even know where they were going until that day. The Messers discuss the case and their theories on what happened to Trenny. Also, Craig & Nick talk about their all-time top 5 TV shows.
