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 battle cruiser model and wrote the line to cover it up.

Transporter beams cannot penetrate shields, yet Kirk is able to beam to the Romulan flagship and back. This means that the Enterprise and the Romulan warships have their shields down, an unlikely scenario with hostile warships facing one another. See more »

The Mission of the Enterprise is Impossible
6 January 2007 | by (United States) – See all my reviews

The "Mission:Impossible"-style entry of the original series, dealing with espionage and subterfuge and con games of galactic proportions. This is the return of the Romulans ("The Deadly Years" doesn't really count) after their smashing debut in "Balance of Terror." It's small wonder that this race is a favorite among Trek fans; both their original episodes are particularly strong. At the start of the episode, we learn, via an echoing voice-over from McCoy, that Kirk has been behaving oddly, as if the stress of command had taken its toll. Indeed, when I first saw this as a kid, I thought, by the end of the first act, that - yep, Kirk's lost it; he's really sailed over the edge in this one; all those conflicts with Klingons, Kelvans, crazy computers, space amoebas, cloud creatures, disembodied brains, doomsday machines and Tribbles have finally produced some post-traumatic stress syndrome in the poor captain's psyche. Yep, it was only a matter of time - Kirk isn't invincible, after all. It was a great set-up: both on the audience and on the soon-to-be hapless Romulans. They're cool here, as to be expected, but when up against the likes of both Kirk & Spock in full 'special mission' mode, they have no chance. These two have altered the cultures of entire planets, after all.

This episode also represents an interesting insight into the culture and social politics of our sixties decade. Here we meet a commander, of either captain or commodore rank, who is (surprise) female; this was unprecedented back then, yet she is on the Romulan (the enemy) side. On our side, the Federation, females up to this point filled such occupations as yeomans and nurses only, with the occasional prosecutor and communications assist. This appeared to be all that was allowed by the powers-that-be until then, as indicated by the rejection of the 2nd-in-command female officer from the first pilot, "The Cage." So, it seems as if Roddenberry and the writers sneaked in this high-ranking female because a supposed villainess or enemy of high rank was deemed acceptable by decision makers - let the enemy indulge in these strange promotions and see what happens. Well, as it happens, it worked against the Romulans: it was unusual to see Spock in the role of seducer, the part usually played by Kirk (who also reverted to his crazy-eyed bonkers routine here, recalling the excesses of such episodes as "The Enemy Within"). This was a fine thriller all-around, with unexpected twists and turns during each act, such as the unveiling of the Vulcan death grip technique, up to and including the conclusion. Oh, yeah, and Spock gets slapped again (his mom did the honors back in "Journey to Babel").
