In Wildwood Tennessee, an outbreak of a mysterious illness resulted in rapid onset symptoms resembling hepatitis. All infections were fatal. Six children and two adults have died. The two adults belonged to a research team from the University of Tennessee. They all participated in a local community picnic celebrating the recent discovery of Native American ruins believed to be of Cherokee origin by the team of researchers. The connection may be coincidental, but a team of Delta Green agents heads into the small town to get some answers.
