The Klingon moon Praxis explodes. This causes the Klingon home world to look at making peace with the federation due to the fact that in 50 years they will have no more air. The ship chosen to escort the Klingon Chancellor Gordon (David Warner) is the Enterprise. The crew of the Enterprise includes Captain Kirk (William Shatner), Science officer Spock (Leornard Nimoy), Dr. McCoy (DeForest Kelley), Scotty (James Doohan), Chekov (Walter Koenig), Sulu (George Takei), and Uhura (Nichelle Nichols). This crew has been together for many a mission and it was an honor to be chosen to do this or was it. Not everyone was happy with the upcoming peace talks. Captain Kirk was definitely not a fan especially after a Klingon killed his boy.
The two ships were traveling along when the Klingon cruiser was attacked and Gordon was killed. Kirk and McCoy were on the Klingon cruiser and they were arrested for the murder. All the facts were pointing at the Enterprise and so the two were sent to prison.
Spock knew that they didn't kill the Chancellor and he started an investigation. His findings were that it was an inside job. Romulans and Federation both didn't want to make peace and there was an effort to derail the peace talks. There were even those from the Klingon Empire who didn't want to make peace. So do they get Kirk and McCoy out of Prison? Do they save the peace talks? you must watch the end of the movie to find out.
Director Nicholas Meyer does an excellent job in this final mission for the original crew of the Enterprise. It has been a long ride for this crew and they brought us into the a world of imagination that no one had ever done before. Thank You!
