It is the anniversary of Cackle's and, while under the influence of a potion, Hettie sets to fulfill a curse which will destroy the school.

Hettie uses trivial magic to bring her dog Kitty back when he is lost but causes havoc when everything lost comes back.

Miss Hardbroom's nephew, Artimus, is staying at Cackle's to study for the "Wiz of the Year" Competition. Mona has also entered the competition, but Artimus tells her that it is only for boys so he and Hettie turn Mona into a boy.

The teachers are put to sleep while a big inspection is going on so Miss Swoop, the only teacher who didn't drink the sleeping potion, steps in to save the day.

The school goes back to basics and cancels their factory-made potion ingredients so the girls can get a taste of being "real witches."

It is Cressie's Hedge Witch training course and she must become friends with her enemy.

The animal inspector comes to inspect the girls' cats, Miss Swoop's owl and Hettie's dog Kitty but Belladonna puts a spell on Kitty to make him bigger than the castle.

Every seven years, there is supposedly a magic wishing well which will grant any wish written on a pebble thrown into the well. But Miss Cackle and Hettie get their wires crossed and as usual Hettie tries to save the day.

Hettie is put on a final warning, so she takes an obedience potion. Belladonna and Cynthia find this out so use it to get Hettie expelled. Mona and Cressie work on a plan to get her reinstated.

The Pentangle's Owl goes missing and Miss Pentangle visits Cackle's to accuse the school of stealing the owl as a form of school rivalry.

The school organises a trip to a theme park but Miss Cackle comes down with what everyone thinks is Witch Fever.
