Star Trek V starts off with the crew taking over the reins of new Enterprise starship, and their first impromptu mission requires them to travel to the near desolate planet of Nimbus III, where a rogue Vulcan known as Sybok (Laurence Luckinbill) has placed several key ambassadors as hostages in order to draw a starship to the planet. His plans are to hijack the ship and crew, taking them on an odyssey to the Great Barrier, a place that no other ship has successfully breached. His mission is to find the Higher Being that all life in the universe refers to as their God, whom he says has beckoned him to be the one to find out life’s eternal mysteries. Is Sybok a madman or a visionary anointed with divine responsibilities?
William Shatner makes his feature-film debut as a director of this maligned entry in the Star Trek movie series.
