Star Trek VI: The Undiscovered Country ( 1991 )
On the eve of retirement, Kirk and McCoy are charged with assassinating the Klingon High Chancellor and imprisoned. The Enterprise crew must help them escape to thwart a conspiracy aimed at sabotaging the last best hope for peace.
What a cracking good end to the Original Series movies - exceptional story, good humour, well-acted, excellent effects, plenty of subterfuge and shenanigans going on to keep you guessing until all is revealed. Well done on creating such a fantastic finale. Worthy of anyone's time and easily watchable over and over. Class movie and I loved it.
