Stardate: 4202.9 --The Enterprise responds to a distress call in the L370 system and discovers that something has destroyed almost every planet in the system.

Elsewhere, they also find its sister ship the U.S.S. Constellation, which has been badly damaged. The commander of the Constellation, Commodore Matt Decker, says that his crew evacuated to one of the pulverized planets and was lost, and the attacker was a giant robot "doomsday machine."

Meanwhile, Kirk is stranded on the Constellation when the doomsday machine attacks again, and the shell-shocked Decker tries to take command of the Enterprise to lead a futile attack.

Log Entries:

  • "Captain's log, stardate 4202.1. Exceptionally heavy subspace interference still prevents our contacting Starfleet to inform them of the destroyed solar systems we have encountered. We are now entering system L-374. Science Officer Masada reports the fourth planet seems to be breaking up. We are going to investigate."



Space: the final frontier. These are the voyages of the starship Enterprise. Its five-year mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before.
