When a Watcher is murdered in the titular "Zone" (a poorly named Seacouver tent city) on the orders of a gaudy mortal criminal named Canaan, Joe enlists Mac's help to stop him. The Rewatchers struggle through the most maligned episode of the series by getting in touch with Charlie's roots, gawking at Canaan's wardrobe, and trying to figure out why Joe is even in this episode.
