In order to save an inhabited planet from being destroyed by a botanical plague, the Enterprise goes to pick up zenite, the mineral cure, on the only known planet where it is mined. When Kirk and Spock beam down, they are attacked by 'troglites' (troglodyte miners) but not captured. High council adviser Plasus intervenes and brings them to Stratos, a luxurious metropolis which literally floats in the sky. However, it is under attack from 'disruptors', troglite revolutionaries who want equal life conditions for their peers. They do all the hard work, mainly toiling miserably in mines and dwell in caves on the barren surface below. Dr. McCoy ascertains that the alleged intellectual inferiority of the troglites is not genetic but the reversible effect of exposure to an invisible gas emitted by the zenite. Written by

Plasus rules as a cruel dictator over Ardana, suspending civil liberties and hoarding resources. This is contrary to the justice- and fairness-oriented ways of the United Federation of Planets. As Ardana is part of the Federation, the Prime Directive does not apply in the matter. Plasus is a criminal and Kirk & Spock are officers of the law. They waste valuable time negotiating and working out deals with Plasus when they have a legal obligation to arrest him and return the hoarded resources to their rightful owners. See more

The captain will employ his usual diplomatic balm.
