Each episode uncovers a single mystery creature. Some have a basis in reality, like the giant fresh water fish that occasionally menace swimmers in the Great Lakes. Others may be the result of terrified imaginations, like India's world-famous Monkey-Man. Still others are grotesque attempts at creation, like the super-soldiers Stalin's scientists tried to engineer by crossing humans with apes. Science and technology come together to gain greater understanding of a mysterious phenomenon -- Bones are analyzed, and key pieces of "proof" are submitted to a battery of tests. Instead of relying on grainy archival footage, we are on-location actively seeking answers.
