Kirk, McCoy, and a crewman named Darnell beam down to a planet (M-113) to   
   visit Robert and Nancy Crater and give them medical exams.    
      
   Great moments: Nancy looking like a youngish woman with dark hair to her   
   former boyfriend McCoy, an older woman with dark hair to Kirk, and a blonde to   
   Darnell.  Soon, Darnell is panting after Nancy.    
      
   Darnell turning up dead with blotches all over his face.    
      
   Spock scolding Uhuru over a frequency error, and Uhuru joking that if she   
   hears the word "frequency" one more time, she will get sick.    
      
   Darnell died from a sudden loss of salt.  Meanwhile, the Craters are asking   
   for salt.  This makes Kirk suspicious.    
      
   Soon, two more crewmen are dead from salt deprivation, then Nancy assumes the   
   form of one of them to infiltrate the Enterprise.  Nancy isn't Nancy.  She's a   
   salt vampire who had replaced the real Nancy after killing her.     
      
   Robert Crater finally explains that the creature (salt vampire) that has been   
   preying on Enterprise crewmembers and emulating them is the last of its kind.    
   The salt vampires have run out of salt, and there is only one left.  Robert   
   compares the salt    
   vampire situation to the extinction of the buffalo.  He doesn't want to kill   
   the last member of an intelligent species.  Kirk points out one difference:   
   The salt vampire has been killing people.    
      
   It seems to me that killing the salt vampire is totally unnecessary.  Just   
   keep it fed with salt (as suggested by Robert Crater and the salt vampire in   
   McCoy form), and its harmless.  Why don't Kirk and Spock seem to take that   
   option seriously?
