A herald appears on Gretta's doorstep, inviting Dwight and Gretta to attend a medieval trial at the Swine & Slosh where the defendant is a cow accused of raucous behavior. Hexela and Baldric find themselves trapped by Madgie the Witch who won't leave Baldric alone until her offer is accepted.

Sightings of a large creature in Woodside Lake rouse the suspicions of Zack, the school newspaper editor. Dwight and Gretta are recruited to help, only to find out that the creature is Winnie the Wyvern with an urgent message for Dwight.

Dwight, Gretta, and Zeke investigate the dozens of mysterious holes that are being dug in Woodside for no apparent reason. Clues lead them to Mr. Dale, who is in shambles and about to crack. Hexela and Baldric track a Tovenar and learn that the end of the world is nigh. Dwight and Gretta go with Mr. Dale to the Swine & Slosh Tavern to retrace his steps.
