Trek to Madworld

The "U.S.S. Enterprise" is ordered to proceed at maximum warp to Epsilon Delta 4, where 700 colonists are slowly dying of radiation poisoning. At the same time, the Romulans and the Klingons have a chance to obtain an unstoppable weapon. Torn between preventing the Romulans and Klingons from upsetting the galactic balance of power forever, and saving the 700 colonists, Captain Kirk faces the most difficult decision of his career.
