After an ecological disaster the future of the Klingons is in doubt; there only chance of survival is forging a peace with the Federation. A reluctant Captain Kirk is ordered to take the Enterprise to a rendezvous point and escort the Klingon chancellor to the peace conference. They meet and have a dinner together then, shortly after the Klingons return to their ship, it appears as though the Enterprise is firing on them even though nobody on the bridge is giving any such orders. In the immediate aftermath two men in Star Fleet uniforms beam aboard the Klingon vessel and shoot many people including the Chancellor before leaving again. Wishing to prove their innocence Kirk and Dr McCoy beam over to help but are arrested and ultimately jailed on a frozen penal colony. If they are to survive they must escape from their prison and their colleagues aboard the enterprise must find out who is the true villain behind the attempted sabotage of the peace conference.
Too my mind this is one of the best 'Star Trek' films. The story is top notch; providing good reasons for the events we see. This leads to plenty of action scenes; a sense of peril, especially for Kirk and McCoy; and, something we don't usually get in 'Star Trek' films... a mystery. This mystery means that much of the fil can be looked on as a sci-fi police procedural/spy thriller as the crew sift the evidence, hunt down clues and close in on the real culprits. While the identity of the most important of these culprits wasn't too surprising their motivation wasn't quite as villainous as one might expect. As well as action and mystery there were moments of humour; notably a Klingon warrior who constantly quotes 'the Klingon playwright' Shakespeare! The cast does a fine job; as one would expect all the regulars impress in their established roles; also notable are Kim Cattrall, as Lt. Valeris; David Warner, as Chancellor Gorkon; Christopher Plummer as Chang and Iman as the shapeshifting prisoner Martia. While only in a small part it was fun seeing Michael Dorn, who will later play Worf, as the Klingon lawyer representing Kirk and McCoy at their trial. Overall I'd say this is a must see for all Star Trek fans.
