Episode Summary & Review
Summary
Enterprise discovers the wreck of Constellation, a sister ship. The only survivor is Matt Decker, the Captain. He reports beaming his crew down to the fourth planet – except that there is no fourth planet! He investigated an odd occurrence: a planet apparently disintegrating, and discovered an immense space vessel cutting the planet apart with an antiproton beam, and digesting the pieces! This machine came from outside the galaxy, a relic of a devastating war fought long ago and far away. It will carve a path of destroyed solar systems through the most populous part of the Milky Way unless Kirk and his crew can stop it.
Our Take
An all time great. If you sample one episode of Star Trek: The Original Series, make it this one.
