Darrin's latest client wants to use a stereotypical ugly witch to promote his Halloween candy. Samantha is understandably upset, as are Bertha, Mary, and Aunt Clara, a trio of elderly witches who have dealt with prejudice for quite some time. When Darrin is fired for creating a campaign with a beautiful, curvaceous witch, the foursome teams up to give the client a taste of his own medicine.

Aunt Clara comes to visit when Samantha meets Darrin's parents or the first time, his mother, Phyllis feels pushed aside, but his father Frank likes Samantha, thinking she's a lovely girl. When her daughter-in-law serves a magnificent dinner, Samantha confesses that it was actually Aunt Clara who helped her with the food, and that she is still learning how to be a magnificent cook.

When a depressed Aunt Clara volunteers to babysit for a friend of Samantha and Darrin's, her magical tricks with toys and games make her a success, and she quickly becomes the most popular caretaker in the neighbourhood. But after she tells her charges that she is a witch, a suspicious mother brings her before a judge for a competency hearing.

The second season of the ""witch-com"" begins with wonderful news: Samantha is about to have a baby! Now, if she can only find Darrin, who's been changed into a chimpanzee by Aunt Clara...

The Stephens have to help out a man named Adam Newlarken who is doomed to be a thief if he doesn't break a two-hundred year old spell placed on his family. He ends up having to do Jackass style tricks to free him from the curse. It gets really serious when he ends up with a whole lot of money, which is coincidentially the exact amount his bank is missing that day!

As a result from a black Peruvian rose, Samantha starts getting sick and loses her powers. She ends up getting green spots all over her face and needs a remedy with a rare ingredient, an ostrich feather. Just when you think that getting the ostrich feather was all they needed, it turns out that they also need the petals of the dreaded rose to make Samantha feel better again.

Samantha and Darrin need some new formal wear for a dinner party that Larry is throwing for a new client, Charles Barrows. And who supplies the beautiful clothes for them to wear? Aunt Clara, the witch with the missing links. Everything goes well, until the clothes start disappearing off the backs of the Stephens. Also, Darrin gets in trouble not only for parking in front of a fire hydrant (Aunt Clara moved the hydrant earlier, but when the clothes started wearing off, the hydrant wnet back to the original place), but for a charge of indecent exposure!

Aunt Clara is embarrassed when an old boyfriend Hedley Partridge comes to see her. She is afraid that he will not talk to her because her magic is fading away, but she learns that he has the same problem, too.

Aunt Clara visits and believes her powers have finally blown a fuse, but in truth, Tabitha is the culprit. Samantha sends Aunt Clara home. Without a baby sitter, the Stephens invite the Tates over to their house. Darrin is convinced the floating objects are the result of Clara's power failure until he pratically catches Tabitha in the act. The Stephens decide to make Larry believe he's had too much to drink in hopes he and Louise will leave before the night is a complete disaster.

The Witches Council orders a coven. Tabitha is being tested for her powers by Hagatha and Enchantra, Endora's sisters who certifies true witches and warlocks. Tabitha passes with flying colors, proving to be an exceptionally talented witch. Hagatha, Enchantra and Endora insist that Samantha enroll Tabitha in a witches' school. After being booby trapped by phone cords and flat tires, Darrin comes home exactly when the decision is made. Darrin, Samantha and Aunt Clara stand against Hagatha, Enchantra and Endora, but Maurice chills the three witches--zapping them to the top of Mount Everest.

Samantha is babysitting little Jonathan Tate, and Aunt Clara turns him into a set of twins. Now how are we going to explain this to the Tates? While Aunt Clara tries to remember the spell, Samantha does everything to keep Larry and Louise from knowing that they have an extra son.

Hey, who turned out the lights? Aunt Clara knocks out the entire Eastern Seaboard's electricity with her magic. Her only hope is her old boyfriend Ocky, who can keep the lights on by having his arms raised. Since they are the only house that mysteriously has power, The Tates and their new client Mr. MacElroy go over to Sam's house. Aunt Clara tries her best to keep Ocky hidden from view by hiding him in the closet. Darrin discovers him, but all he sees is a pair of walking shoes, a perfect campaign for his client!

Aunt Clara tries to help Samantha fix a lamp, and conjures an electrician, none other than Benjamin Franklin. Darrin is amazed at Franklin's appearance and Larry thinks it is a great advertising campaign for his new client Franklin Electronics. Samantha agrees to take Franklin out to demonstrate how his inventions are used in the twentieth century, but he goes out alone! After a mishap with a fire engine, Ben is arrested. Out on bail, the Stephens return home, but now, Ben disappears! Clara has remembered the spell........ to be continued.

Aunt Clara remembers the spell to bring Franklin back when nosy Gladys Kravitz tells all about the Stephens' happenings. It seems that Franklin will be punished to the full extent of the law when Larry tells about how great a publicity stunt it is, with the District Attorney listening! With a little bit of magic, Samantha gets the people to root for Ben Franklin. In court, Samantha tells everyone that Ben Franklin has done no harm ever since he appeared and that he cannot be accused for stealing his own property. The judge drops all charges and Franklin is free to go.

Samantha applies for a loan to tear down a gazebo and to construct a rumpus room. The nosy bank inspector comes down to check out the land and sees a live baby polka-dotted elephant mistakenly conjured by Aunt Clara. The baby elephant was from a toy that Tabitha had wanted in the park. Larry comes by to see what the fuss it all about, and Samantha tries to hide the big baby from him.

Aunt Clara thinks that she is worthless and barren and wants to turn herself into something useful. Samantha discourages her from abusing herself and invites her to go to lunch with Darrin. At Darrin's building, Samantha leaves for a moment and Aunt Clara finds a seat in a covered-up display and falls asleep. Meanwhile, a policeman and a animal handler are fighting about having a cow in the building. This cow is actually the Morton Milk cow and it runs off. Samantha comes back to see this cow and thinks that Aunt Clara made good on her threat. She twitches the cow home to try to turn her back into her beloved aunt. Back at the building, the cow ends up missing and Darrin finds Aunt Clara. Samantha notices her mistake and returns the cow to its rightful owner.

Aunt Clara's morning paper says that Larry Tate breaks his leg while on a honeymoon with Louise.
