After the Enterprise destroys a mysterious cube blocking their journey, the crew find themselves confronted by a gigantic spaceship whose commander threatens to destroy them.
In the first episode filmed after Star Trek was ordered to series, we see the debut of the familiar uniforms of the Enterprise crew for the first time, the characters of Dr. McCoy, Lieutenant Uhura and Yeoman Rand are introduced, and Fred Steiner's score presents some familiar music cues we'd hear in multiple episodes. Jerry Sohl's script also features elements that would reverberate throughout the series, from McCoy's questioning of Kirk's judgements, to the captain's coolness under pressure that melts a junior officer, and Kirk risking his ship and crew on a dangerous bluff. Listen for the voice of Ted Cassidy (The Addams Family's Lurch) and watch for Ron Howard's brother Clint.
