The Enterprise is ordered to clean up the aftermath of a doomed colony on Omicron Ceti III, a planet under constant irradiation from deadly Berthold Rays. Upon arrival, however, the colonists aren't only alive but in perfect health, with no desire to leave their new world. They are in fact under the influence of plant spores which not only keep them in good and improved health but simultaneously keep them in a placid state of happiness and contentment. Mr Spock reacquaints with Leila Kalomi, an old friend who had been (and still is) in love with him. She leads Spock into being affected by the spores, and he is thereafter, for the first time, able to express love for her in return. Eventually the entire ship's crew is affected, leaving Kirk alone to wonder how he can possibly rescue them from perpetual bliss. Written by

According to director Ralph Senensky, the original schedule was that the first three of the six shooting days were to be spent on location, shooting at the Golden Oak Ranch (also known as the Disney Ranch), then the remaining three days indoors, filming the Enterprise scenes. However, after two days of shooting outdoors, Jill Ireland fell ill and couldn't appear on the set. It was in question if she had measles or not. Senensky decided to film all the farm scenes which didn't contain Leila's character and then return to the studio for Enterprise interiors in the remaining of the day, and hope for the actress' return. Ireland appeared the following day, as it turned out that she did not have measles. However, the crew couldn't return to Disney Ranch as it was already booked for another production. They decided to film the remaining scenes at Bronson Canyon. See more

Well, if we're both in the brig, who's going to build the subsonic transmitter?
That is quite logical, captain.
