Introduction
Captain Kirk thinks he found the infamous Kodos the Executioner living under an assumed identity as an actor in a traveling troupe. Twenty years ago, Kodos seized control of the colony on Tarsus IV. The colony was facing a food crisis threatening its 8,000 residents. Using his own version of eugenics, he selected 4,000 colonists to die so that the other 4,000 might live. When Federation forces eventually retook the colony, they found only a corpse burned beyond recognition. Only 9 of the surviving members of the colony saw Kodos, and they are being killed one by one. The two remaining eye witnesses to the massacre are one of the Enterprise's engineers...and her captain.
