After a productive summer break, Wednesday returns to Nevermore as a grudging campus celebrity and the target of a dangerous stalker. 

Chaos reigns on campus as Nevermore celebrates its annual Prank Day; Wednesday confronts an old enemy and gains an unwanted ally. 

Stripped of both her ability and Goody's book, Wednesday is forced to do some old-fashioned detective work on a school camping trip. 

It's an Addams family investigation as Fester and Thing commit themselves to Wednesday's case; trying to conceal one secret, Bianca stumbles on another. 

With Tyler on the loose, Wednesday readies for a risky Día de los Muertos showdown; Slurp's growing hunger poses problems for Pugsley. 

An encounter with a spirit from Nevermore's past gives Wednesday and Enid a new perspective on one another, and puts one of their classmates in danger. 

As the school gala looms, Wednesday digs up dirt on Dort; Enid tries not to wolf out; Morticia engages in a battle of wills with Grandmama. 

When buried family secrets are unearthed, Wednesday must race against time to prevent a dark prophecy from being realized.
