The USS Enterprise is sent to observe Planet Nibiru, but finds a volcano on the verge of erupting and wiping out its primitive inhabitants. In the process of launching a dangerous mission to halt the eruption, first officer Spock's life is jeopardized, forcing Kirk to break the "Prime Directive" and reveal the Enterprise to the planet's civilisation to rescue him. As a consequence, a number of indigenous people begin to worship the ship as it leaves. After being called back to Earth, Kirk is relieved of command, and Admiral Pike re-assumes command of the Enterprise. Shortly afterward, Starfleet agent John Harrison bombs a secret "Section 31" installation in London. An emergency meeting of high ranking officers is called at Starfleet headquarters, which Kirk attends as Pike's first officer. The meeting is attacked by a gunship piloted by Harrison. Kirk takes the gunship down, but Harrison escapes and Pike dies.
After Pike's funeral, Admiral Marcus (Weller) authorizes Kirk to hunt down Harrison, who has fled to the Klingon homeworld of Qo'noS. Since Qo'noS lies deep in Klingon territory and Starfleet is on the brink of war with the Klingon Empire, the Enterprise is supplied with 72 long-range prototype photon torpedoes, and is ordered to fire them all at Harrison's location once he is found. Believing the torpedoes could be dangerous to the ship, chief engineer Montgomery Scott refuses to take them aboard and tenders his resignation when ordered to accept them. The Admiral's daughter, scientist Carol Marcus also joins the crew, under a false identity, and Pavel Chekov is promoted to Chief Engineer.
With Marcus in pursuit, the Enterprise is attacked by the superior starship Vengeance in Earth's orbit. Outgunned, the Enterprise is severely damaged. Ultimately Kirk agrees to hand over the Klingon Khan and the 72 bodies in cryo sleep in exchange for the lives of his crew. Marcus refuses and beams his daughter aboard to prevent her being used against him.
