Throughout history there have been those who have just seem to have stepped off the face of the earth to never be heard from again. These people just seem to drop out of existence, sometimes leaving bizarre clues, but just as often leaving no trace behind at all. On occasion there are those cases that go into dark territory, hinting at nefarious dealings and grim outcomes, but never letting these things come up into the light from the gloom within which they dwell. One such case concerns a teenaged girl, who went out in broad daylight only to evaporate from existence, sending authorities and her mother on a chase through dark waters and a criminal underworld in a futile search for answers.
