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?


The Romulan cloaking device prop was created using the Sargon globe (Star Trek: The Original Series: Return to Tomorrow (1968)) and portions of the Nomad probe (Star Trek: The Original Series: The Changeling (1967)). See more »


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: The Original Series: Balance of Terror. However, the cloaking technology in 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 »

... reflects historical events!
28 July 2018 | by jamesvaughanantwerpSee all my reviews

Fascinating! None of the other humans has mentioned how this episode involves events and conflicts which mirror those of real life super-power conflict in the history of your Earth.

Almost nine months before 'The Enterprise Incident' aired a US Navy 'spy-ship' ( the USS Pueblo) was seized off the coast of North Korea. Two of the crew were killed by enemy fire and the remaining 80 officers and seaman were held captive for almost a year. Some prisoners were tortured.

So the idea of 'ships' engaging in secret spy missions was still high on a lot of minds when Kirk and Spock launched their complex plot of subterfuge.

Of other interest in the episode is the rather silly way Romulans dress; as if their entire sense of fashion was based on knitting of grandmothers. Also; in spite of some rather rude jokes- Captain Kirk actually looks quite dashing with pointy ears and eyebrows!

It should be noted, sadly, that the Romulan Commanders fate, once returned to her side of the neutral Zone (given the seriousness of the cloaking device falling into Federation hands) could not have been pleasant!
