While on the Earth to find out how humans live, a group of four aliens - that has taken on the human form - discovers humans are more complex than they had expected. Leader Dick learns human bodies can produce feelings and wants to find out more about these feelings with his colleague, Mary Albright. Tommy has a teenager human body and he - after seeing some volleyball girls practicing - also finds out human bodies can produce feelings, but these feelings are not quite the same as the ones Dick experiences.
