A ghostly Puritan judge named Hebediah Grim begins terrorizing Crystal Cove and judging its female citizens, forcing Mystery Incorporated to investigate. At first, they turn to Gary and Ethan, but both claim to have fought the monster themselves. Ethan suggests Doogle McGuinness, but the monster attacks as the gang are investigating him. Grim then turns his judgment upon Daphne, but Brad Chiles and Judy Reeves offer to help Fred protect her, and they set up a trap to capture Grim. They encourage Fred that he will be a great “trapsman” claiming it is “in his blood” and to believe in himself as they do. It is also shown that Daphne still has strong feelings for Fred, as well as that there are feelings between Mayor Nettles and Sheriff Stone. The episode ends with Cassidy Williams spying on the gang, Brad, and Judy.
