This program contains very graphic and disturbing depictions of encounters with unknown creatures. Viewer discretion is highly advised. Have you ever had the feeling that you were being stalked at night? Perhaps the feeling of some unknown creature lurking within the murky depths of a lake? Welcome to Mysterious Quest, where our worst nightmares are brought to life. Over thousands of years, there have been records of bizarre creatures, which are staved off by scientists as creative imagination and misidentification of animals we are familiar with today. But even trailing into modern times, there are numerous eyewitness reports of these supposedly mythical beasts - and not all witnesses come out unscathed, reminding us that when we end up in the wrong place at the wrong time, we are no longer the apex predator.
