The Enterprise deliberately crosses the Neutral Zone, on Kirk's orders, into Romulan space and is promptly surrounded by Romulan warships, each equipped with a "cloaking device" that renders it undetectable. Spock betrays the apparently irrational and paranoid Kirk to the Romulan commander, a woman who is obviously attracted to Spock. A deadly game between Kirk, Spock and the Romulans risks not only the Enterprise but the tenuous cease-fire between the Romulans and the Federation. Written by Tom D.

Did You Know?


In the opening segment, in regard to the enemy vessels, Spock declares "Romulans now using Klingon design!" The actual reason for this was that in unpacking the models to shoot this sequence, a production assistant stepped on and broke the Romulan Warbird model that was going to be used, so they pulled out their Klingon Battlecruiser model and wrote the line to cover it up.

The Enterprise crew are shocked to learn that their surprise capture may be due to a new cloaking technology possessed by the Romulans. Kirk and crew already encountered cloaked Romulans two years earlier in Star Trek: Balance of Terror. However, the cloaking technology in Star Trek: The Enterprise Incident is new because it is improved. The Enterprise was still able to track a Romulan ship, though not accurately, in "Balance of Terror" and cannot detect them at all with this improved version. See more »

Strategically Interesting
3 May 2014 | by (United States) – See all my reviews

After the ludicrous "Spock's Brain," this is a decent episode, worthy of praise. Kirk puts the Enterprise in grave danger by crossing into the neutral zone. Soon the Romulans are at the door, threatening to take over Kirk's ship. Their ships have been cloaked which poses a threat to the Federation. Kirk responds by threatening to blow up the Enterprise if they don't back off. This leads to an exchange of crew members, Spock going to the Romulan ship. While there, he strikes up a romantic thing with the beautiful Romulan commander. Vulcans and Romulans come from the same roots and she sees him as a potential ally. The reason this works so well is that we are not privy to what Kirk and Spock are up to. Kirk seems utterly insane and Spock seems to be a traitor, but we know, don't we? It is interesting to see someone beside Kirk putting the moves on an attractive female alien. The conclusion is satisfactory and worth the wait.
