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?


Joanne Linville's Romulan Commander is given the name Dion Charvon in a 1977 Star Trek novel called "The Price of the Phoenix", by Myrna Culbreath and Sondra Marshak. In the 1999 novel "Vulcan's Heart" by Josepha Sherman, her name is given as Liviana Charvanek. It's not clear if either novel is "canonical" but Liviana Charvanek seems to have higher authority and credibility. In addition, Diane Duane's 1984 novel "My Enemy, My Ally" states that the commander had her name stripped from her because of the events of this episode, and introduces the commander's aunt, Ael t'Rllaillieu.

In the early second scene in the briefing room, where Spock reveals to the Enterprise officers that the Neutral Zone was breached on Kirk's orders, two officers are shown in the background. One is wearing a gold tunic indicating he is a member of Command or Navigation with commander insignia on the sleeve (holding the same rank as Dr. McCoy and Mr. Scott and outranking both Chekov and Sulu.) Another is a "red shirt" indicating he is a member of Security, Engineering, or Communications and that contains stripes indicating a Lt. Cmdr. ranking (the same as Spock) which would in turn indicate that he outranks both Lt. Uhura and Mr. Scott! No explanation or other identification is provided. See more »

Well Played and Suspenseful Episode
7 July 2006 | by See all my reviews

This is a nicely paced, genuinely suspenseful episode which finds its roots in the best espionage stories. Kirk takes the Enterprise into Romulan territory on his own initiative, leading many to question his competency to command and increasing hostilities with the Romulans. Is Kirk actually losing it, or is something else afoot? This episode resembles some of the best spy fiction -- "The Spy Who Came In From the Cold" in particular -- and Shatner's staginess actually works to the episode's advantage. Nimoy's inscrutability is equally compelling, particularly when the Romulan commander (well played by Joanna Linville) tries to persuade him to join the dark side, as it were.

Intelligently written and played, and a lot of fun to boot.
