Star Trek V: The Final Frontier was the fifth Star Trek movie produced and the fifth based on the original series. The crew of the USS Enterprise-A is sent to the planet Nimbus III in order to rescue the Federation, Klingon, and Romulan ambassadors to the planet from their kidnappers. When the Enterprise arrives, the crew discovers that Sybok, Spock's half brother, is the kidnapper. Sybok then takes over the Enterprise and takes it towards the center of the galaxy in a search for God. Once the Enterprise arrives, the crew and Sybok discover a being with immense power who turns out to merely be a malevolent being, not God.
