Major Harlan Dean (Joe Bob Briggs - 'The Last Drive-In') is the host of the widely popular radio show The Truth Serum, a platform which he discusses all things weird, unknown, and sometimes scary. On tonight's broadcast, Harlan tackles the topic of Cryptozoology to coincide with the annual Mothman Festival in Point Pleasant, West Virginia. However, with each caller, something more sinister appears to be waiting in the shadows and this could end up being Harlan's very last broadcast.
