Although Darrin suspects Endora of using magic to break up his marriage and ruin his reputation at work again, it is actually Samantha's distant cousin Edgar, an elf who has the power to become invisible.

Samantha sets up a play for a rest home to celebrate the end of the Civil War. As she writes, Endora brings her characters to life to help Sam out. Of course, nosy Gladys see all this and goes crazy, as usual. Sam suffers a writer's block near the end of writing, and her play characters lend a hand to tie up the loose ends.

Samantha and Darrin decide to go away for a few days. Larry suggests that they stay at his cabin, which of course, is run down and decrepit. With the help of magic, Samantha turns the eye-sore cabin into a glamorous, to-die-for dream house. It catches the eye of a prospective young couple, and they insist on buying it. Darrin is mad at Samantha and makes her change it back to the eye-sore it once was, but Sam makes the couple seem like they are looking at a beautiful house.

Darrin unknowingly gets three wishes from Endora. He blows the first two on fast elevators and bikini-clad girls, and he wishes that he was Larry for a day. He gets his wish and a whole lot of misunderstanding begins between Louise and the real Larry!

A vacation that the Stephens were supposed to take is scrapped when Darrin has to work. Endora takes it upon herself to separate Darrin into two different personalities: his work side and his fun and spontaneous side. While the working Darrin is concentrating on his job, the fun Darrin is concentrating on partying until he drops. Of course, all of this takes a toll when the Working Darrin bores Larry and his new client and Samantha acts as mother instead of wife to Darrin, the party animal. Samantha wants Endora to put the Darrins back together again, but ends up doing it herself.

Darrin is refused a new account in McMann and Tate, but the next day, Larry gives Darrin the account. Darrin thinks that Samantha used magic to sway Larry's decision and tries to do everything to back out of it. Even the client, Mr. Waterhouse, likes Darrin's attitude and ability. Darrin feels that Samantha is behind all that has happened to him. To teach Darrin a lesson, Samantha uses magic to turn their house into an expensive mansion with servants to boot. Darrin tells Sam that he wants to earn things his own way, which is exactly what he has been doing all along.

Darrin has a bad cold and Dr. Bombay treats him with some pills. Of course, these pills have a horrendous side effect- it makes his voice higher!
