The Starship Enterprise is ordered to check on a Federation colony on the planet Omicron Ceti III. The problem is that the planet is full of flowers that spray spores at people and turn them into idealist who dwell on the concept of love. Spock finds a girlfriend.
Kirk: Maybe we were not meant for paradise. Maybe we were meant to fight our way through, struggle, claw our way up, scratch for every inch of the way. Maybe we cannot stroll to the music of the lute. We must march to the sound of drums.
Spock: Poetry, Captain. Nonregulation.
Kirk: We have not heard much from you about Omicron Ceti III, Mr. Spock.
Spock: I have little to say about it Captain, except that, for the first time in my life, I was happy.
