The leaves have already started to change, but Professor Jonathan Rust is still woefully ill-prepared for the coming semester. This weekend, he is scouting a suitable location for the archeology department's field work course. With the help of fellow academics and hired hands, the team heads out at first light. The trip presents a rare opportunity for Jonathan to get his hands dirty and success could mean publication and just maybe - tenure. The expedition is quickly derailed when a Teaching Assistant mysteriously vanishes. Soon, the group finds themselves at the intersection of reality and the afterlife in a haunting descent into madness.
