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.
