Samantha has embarked on painting as a hobby, and plans on entering her still life painting into a charity art exhibit and competition. Endora will not allow Samantha to sully the family name by publicly displaying anything that is less than a masterpiece. Seeing that Samantha's own creation doesn't live up to that standard, Endora decides to exchange Samantha's painting temporarily until midnight for that of renowned French artist Henri Monchet. Samantha learns what her mother has done when her painting is revealed as the winning entry in the competition, the painting which will be auctioned off to the highest bidder. A further problem arises when perfumer Mr. Cunningham, a client of Darrin's, wants the painting, especially as he sees himself as an art connoisseur. Darrin and Samantha have to try and get him not to bid on the painting while they purchase it themselves. If they can't do so, they have to find a way to get the painting from him before the painting magically disappears at midnight.
