In July of 1995, a 24-year-old woman in Alaska headed out on a date with a man she had only recently met. She was last seen at a crowded summer fair in the forest, surrounded by tourists - but by the time the sun rose the next morning, she was gone. What followed was a desperate search in the unforgiving Alaska wilderness, and eerie silence from her date, which only deepened the mystery. This is the disappearance of Erin Gilbert.
