Flat Earthers. The term is synonymous with conspiracy theorists who sit alone in dark rooms or who wear tin foil hats. Meet real Flat Earthers, a small but growing (and very vocal) contingent of people who firmly believe that there is a centuries'' long conspiracy to suppress the truth that the Earth is flat. One of the most prominent Flat Earthers is Mark Sargent who, in the midst of the upcoming Solar Eclipse, proudly speaks at the first major Flat Earther conference. With astounding access (as well as input from the scientific community), director Daniel J. Clark creates a "well-rounded" look at this fervently passionate bunch, that will surprise and delight.
