Six teams face off for the first time in the main competition, hoping to impress judges Eddie Jackson, Shinmin Li and Aarti Sequeira. If that's not scary enough, Zak Bagans introduces the teams to the haunted city of Salem, Massachusetts, and a coven of witches looking for revenge.

The four remaining teams face another spine-chilling assignment from Ghost Adventures' Zak Bagans. This time, they must conjure up a ghostly rave party for judges Eddie Jackson, Shinmin Li and Aarti Sequeira inspired by the haunted Shanghai Tunnels that lie beneath the bustling streets of Portland, Oregon.
