Accompanying a beautiful, sexy client to Chicago, Darrin begins to act strangely when he suspects that her cat is actually Samantha in disguise.

The new rage on the fashion world is Samantha when she makes up stellar dresses for each of the women in the community using replicas of a fashion designer named Aubert she and Endora went to Paris to check out. Of course, Aubert goes to America and sees his work on display and goes totally up at arms about it.

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.
