After an explosion on their moon, the Klingons have an estimated 50 years before their ozone layer is completely depleted, and they all die. They have only one choice – to make peace with the Federation, which will mean an end to 70 years of conflict. Captain James T. Kirk and crew are called upon to help in the negotiations because of their "experience" with the Klingon race. Peace talks don't quite go to plan, and eventually Kirk and McCoy are tried and convicted of assassination, and sent to Rura Penthe, a snowy hard-labor prison camp. Will they manage to escape? And will there ever be peace with the Klingons?

Did You Know?


In earlier screenplay drafts, the character of Maltz from
Star Trek III: The Search for Spock appeared at the trial as one of Chang's witnesses, answering questions about Kirk's killing of the Klingon crew from that film. The scene was dropped as it was deemed extraneous, and John Larroquette was unavailable to reprise the part anyway.


At the beginning of the film, when the Excelsior encounters the energy wave created by the explosion of Praxis, Sulu's hair goes from being neatly groomed to mussed up back to neatly groomed between shots.

Captain Hikaru Sulu:
Stardate 9521.6. Captain's Log, USS Excelsior. Hikaru Sulu commanding. After three years, I have concluded my first assignment as master of this vessel, cataloguing gaseous planetary anomalies in Beta Quadrant. We're heading home under full impulse power. I'm pleased to report that ship and crew have functioned well.

User Review

A fitting end for the crew of the NCC-1701-A.

Rating: 9/10

The journey that began on the small screen in 1967 comes to its end on
the big screen in 1991, after three TV seasons, six films, and the
creation of a cultural phenomenon unrivaled in the history of
television. The crew of the original series had met with mixed results
on the big screen, producing the excellent The Wrath of Khan, but also
the inexcusably bad The Final Frontier; the other four ranged from
passable to good. After the financial failure of Star Trek V, Paramount
brought back Star Trek II director Nicholas Meyer, and commissioned
from him the final voyage of the original cast. As Star Trek so often
does, the events depicted mirror the glasnost of the late 1980s, as the
collapse of the Soviet Union eased global tensions and heralded the
beginning of a new era. In the Trek universe, the possibility of
rapproachment between the Federation and the Klingon Empire raises the
hackles of hardliners on both sides, and Kirk and co. must prevent the
weak peace from being destroyed. The original cast is in fine form, all
of them giving their all to make the (potentially) final appearances of
their characters memorable. Despite William Shatner's reputation as a
ham actor, he delivers a great performance here; his final log entry is
one of Trek's finest moments. As the villain of the piece, we get
General Chang (Christopher Plummer), a Klingon out to insure "no peace
in our time". Plummer is superb, chewing scenery and spewing
Shakespeare with a wonderfully loathsome presence. I would rank Chang
below Khan and the Borg Queen, but far above all the other Trek
villains. There are some tacky anachronisms typical of Meyer's style,
and the usual amount of discontinuities and canon issues; but that's
inevitable, and I can accept it if it leads to a good story. Trek VI is
a good story. 9/10.
