When a reptilian alien race known as the Gorn destroys an Earth colony, the Enterprise comes under attack by the Gorn vessel. Captain Kirk soon gives chase to the Gorn ship, leading them to an unexplored solar system, gradually (and dangerously) increasing speed. Kirk prepares to destroy the Gorn ship until another race of powerful aliens called the Metrons stops them and forces both captains to face off in mortal combat. The main purpose of this one-on-one duel is to solve their dispute, the winner will be released and the loser will be destroyed along with his ship and crew. Written by Anonymous

While the crew is watching the picture the Metrons provide on the view screen, the picture noticeably shifts up and down in the frame of the screen, apparently due to a poor (or hastily done) video overlay. See more »


[first lines]
Captain James T. Kirk: You'll enjoy Commodore Travers. He sets a good table.
Dr. McCoy: I wonder if he brought his personal chef along with him to Cestus III.
Captain James T. Kirk: Probably. Rank hath its privileges.
Dr. McCoy: [they both chuckle] How well we both know that!

A very good episode despite really awful special effects
6 December 2006 | by (Bradenton, Florida) – See all my reviews

This is a very good episode with a very good plot. The only problem for me is that the enemy (the Gorn) is really cheesy-looking--the head barely moves and looks like a crummy mask. Not terrible by 1966 standards, but today it looks pretty poor.

Now as for the plot, it really rocked. The Gorn attack a Federation outpost and kill practically everyone with their super weapons. The Enterprise has no idea who these enemy are but they know they MUST kill them or risk further attacks. However, in pursuing them, they enter Metron space and these advanced beings are horrified by the seeming brutality of these two races. So, to end the problem, they place the captains of BOTH ships on a barren planet and let them fight to the death--and the loser's crew will then be destroyed.

Despite a relatively simple plot, the episode has three different locales and is a good showcase episode for Kirk. Not the best, but definitely among the better episodes made.
