On a lark but also on the urging of her mother-in-law, Samantha enters a slogan contest, the first prize which is a trip for two to Tahiti. A surprised Samantha wins the contest. What she is unaware of is that the company for which she submitted the winning slogan is a client of Darrin's.

As a joke Uncle Arthur switches Sam and Darrin's voices and can't seem to switch them back. Unfortunately Louise Tate is visiting due to a fight with Larry.
