In the second Halloween episode of the series, Endora turns Darrin into a werewolf when he refuses to let Samantha go to a witches Halloween ceremony. The worse part of it is, Darrin has to entertain a new client for McMann and Tate! Samantha tells Endora that she is acting like the witches stereotype, and Endora removes the spell.

Endora invites Darrin and Samantha to a wedding out of town, but Darrin is not sure that Larry will give him a day off. Endora thinks about turning Larry into an object, but thinks better of it when she asks Larry to let Darrin go. Endora learns that he is looking for a teddy bear for his son and she brings a teddy bear to his office. Darrin thinks the worst when he sees the teddy bear sitting in Larry's office, and after a series of misunderstandings, everything clears up when Larry actually walks in! It seems that Larry was out somewhere and Endora left the teddy bear in his office while he was out.

Darrin is sure to get the Robbins Baby Food account, but Mr. Robbins wants his home life checked out. His assistant, George Barkley, wants to check out a little bit more of Darrin's life so he hires sneaky, sly Charlie Leach to spy on him. Samantha uses her magic one day and Abner's sister, Harriet Kravitz (who conveniently takes care of the house while Gladys is away), catches her and tells Charlie all about it. He doesn't believe it at first, but he catches Sam using her powers. He tells Samantha either she tells him what he wants to jknow or he will tell the entire world that she is a witch.....

Charlie Leach really has something over Sam's head. Charlie wants Sam to give him and his wife Charmaine an expensive apartment with an expensive car to boot. Darrin finds out about how Barkley started this whole mess and decides to cancel the Robbins account. At Robbin's office, while Darrin is telling Robbins and Barkley where to go, Samantha uses her magic to expose Barkley and gets him fired. One down, and one more to go when Samantha goes to Leach's apartment and destroys everything with her magic. When Leach finds out, Samantha twitches him to Mexico. Leach vows that he will be back....

Samantha insists that Endora zap away the new pony for Tabitha before Darrin gets home. Endora tells her not to worry, the pony IS Darrin. Once changed back, Darrin orders Endora out of the house.

At the office, Endora sends a ""live"" framed photo of her that Darrin cannot escape her ever changing expression. A client named Mr. Gregson wants to meet Darrin's mother-in-law, who must be a special woman for Darrin to keep her photo on his desk. The dinner goes well, particularly since Endora has become the queen of charm. After witnessing a tiff between the Tates over Larry's mother-in-law, Gregson suggests that Darrin should open his own ad firm. Larry doesn't like this one bit and refuses to speak to Darrin. It's up to Samantha to set things right between Larry and Darrin.

Samantha, Endora, Tabitha and their warlock cousin Henry spend a day in a department store. Henry is offended by a salesman, and he turns the salesman into a mannequin and refuses to change him back. Samantha and Endora try everything, but Tabitha remembers the spell and restores the saleman.

In this crazy episode, Samantha gets a condition which makes her entirely 500 pounds heavier. Dr. Bombay comes and gives her an antidote that makes her lighter...a little too light as she floats to the air! This will be hard to hide when the Prescotts, McMann and Tate's newest clients, has Samantha volunteer for a charity bazaar and fashion show. Sam tries everything to help weigh her down, but to no avail. In a memorable scene, Samantha holds a giant urn on her shoulder as she goes down the runway half floating, half walking in the fashion show. It is there that Darrin comes up with a spectacular slogan for Prescott shoes.

The Washingtons adjust to life in the twentieth century as they stay with the Stephens. Larry sees them both and decides that it is a great ad campaign for his new clients, the Whirlaway Washing Machine Company. George cannot tell a lie about the washer and, as a result, loses the account for Larry and Darrin. He does the same thing in the courtroom and his charges are dismissed. Then the Washingtons are finally send back to their own time.
