Star Trek V: The Final Frontier

Star Trek V: The Final Frontier is a 1989 film released by Paramount Pictures and the fifth feature film based on the Star Trek science fiction television series. The film was directed by William Shatner, following two films directed by his co-star, Leonard Nimoy. Shatner also developed the initial storyline. It was shot entirely on location in California.
The year is 2287, and following the events of Star Trek IV: The Voyage Home, the crew of the USS Enterprise (NCC-1701-A) is on break enjoying shore leave, as the newly built starship's shakedown cruise goes poorly while it undergoes repairs in spacedock. On planet Earth at Yosemite National Park, Captain James T. Kirk is on a camping trip with half-Vulcan First Officer Spock and Dr. Leonard McCoy. Their leave is interrupted when the Enterprise is ordered by Starfleet Command to rescue Terran, Klingon and Romulan hostages on the desolate planet of Nimbus III; also referred to as the Planet of Galactic Peace. Learning of the Enterprise's mission, the Klingon Captain Klaa aboard a bird-of-prey, the Okrona, with the encouragement of his First Officer Vixis, decides to engage Kirk in combat for his own personal glory after growing tired pursuing and targeting derelict space debris.

Upon arrival at Nimbus III, the Enterprise crew discovers that a renegade Vulcan named Sybok (who is later revealed to be Spock's half-brother), is behind the hostage crisis. Sybok demonstrates that the hostage situation was a ruse to lure a starship to Nimbus III in order to reach the mythical planet called Sha Ka Ree, the place from which creation began. Sha Ka Ree is located behind a seemingly impenetrable barrier near the center of the galaxy. Sybok uses his unique ability to reveal the innermost pain of a person and help them emotionally heal themselves, in a bid to gain the trust of both the hostages and crew members. While McCoy and Spock agree to interact with hallucination imagery, Kirk refuses Sybok's offer, telling him that his emotional pain is part of what makes him human. Later however, Sybok reluctantly decides to declare a truce with Kirk, realizing he needs his leadership experience to navigate the Enterprise to Sha Ka Ree.

The Enterprise successfully breaches the barrier pursued by Klaa's vessel, and discovers a lone blue planet. Sybok, Kirk, Spock, and McCoy journey to the surface, where Sybok calls out to his perceived vision of god. An entity appears, and when told of how Sybok breached the barrier, demands that the starship be brought closer to the planet. When a skeptical Kirk inquires, "What does god need with a starship?", the entity attacks him in retribution. McCoy in turn, begins to realistically doubt the entity as a god who would purposely inflict harm on people for pleasure. The entity then tries to exploit the Enterprise; requesting to "Join with it", in an attempt to depart the surface. Soon Sybok starts to distrust the entity as genuine, at which point he suddenly sacrifices himself in a physical struggle with it to help the others escape. Kirk then orders the Enterprise to fire a photon torpedo at their location killing Sybok while simultaneously disabling the entity. Later, Spock and McCoy are beamed back to the ship, but Klaa's vessel attacks the Enterprise before Kirk can be transported aboard.
On the planet below, Kirk is about to be killed by the entity when Klaa's vessel destroys it in a barrage of disruptor fire. Kirk is beamed aboard the bird-of-prey and learns that Spock and the Klingon hostage (General Korrd), have forced Captain Klaa to stand down. A reception is held aboard the Enterprise with the Klingons to celebrate the new détente, as Kirk, Spock and McCoy return to their vacation at Yosemite.
