The pharmacist lives a happy but monotonous life. His apartment is above the pharmacy, his wife cooks for him and in the afternoons he works in the pharmacy so that he can devote himself to his research in the laboratory. His wife's attempts to attract a little of his attention are futile. So she finds an old recipe for a love potion, plucks herbs and the man drinks the drink. The pharmacist makes his Formula III, or rejuvenating cream, and unknowingly uses some of the concoction. When he and his wife go to a brewer's ball, strange things begin to happen.—EuroFan
