Breaking into the facility, they find themselves confronted with a number of terrifying obstacles, including a group of supernatural assassins hired to protect the scroll.

Amid this chaos, Stiles' condition continues to deteriorate, and the pack begins to suspect that his hallucinations may hold the key to finding the Nogitsune and defeating it once and for all.
