In a classic Keith episode of Dateline, a rural Michigan community searches for a young woman last seen at a Halloween party. The party took place on acres of farmland with hard rock bands, plenty of alcohol, and no guest list. 22-year-old Chelsea Bruck went to the party with her girlfriends, but they left without her. She had been so excited about having fun in her homemade Poison Ivy costume, but the party did not go as planned. Alone, crying, and without transportation in a crowd of hundreds of partiers, Chelsea was a vulnerable target for a predator. Join Keith as he leads us through the investigation, finding her killer, and reliving the real horrors of Chelsea Bruck's last party.

Happy Halloween and be careful out there, kids!
