'Spaceplex' is 9 year old Katie Beers’ favorite spot, before she’s abducted at that same location in December 1992, just before her birthday. For 17 days, the investigators dig into the family’s lies, each more suspicious than the next, hoping to find the lost girl. Katie is trapped in the wall, but she still has her wits, which will eventually lead to justice against her kidnappers.
