Star Trek Into Darkness

In the year 2259, the Federation starship USS Enterprise has been sent to the planet Nibiru to study the development of primitive cultures. Captain James T. Kirk and Executive Officer Spock attempt to save the planet's inhabitants from a volcanic eruption. When Spock's life is endangered, Kirk violates the Prime Directive, exposing the Enterprise to the planet's civilization in order to rescue Spock against his will. Kirk and Spock have a major falling out over this decision.

On return to Earth, Kirk loses command of the Enterprise because of his decision and Admiral Christopher Pike is reinstated as the commanding officer. When a secret Section 31 installation in London is bombed, Pike, Kirk, and Spock meet with Starfleet commanders to discuss the hunt for the culprit, rogue Starfleet agent John Harrison, but Harrison attacks the meeting in a jumpship. Kirk destroys it, but Pike is killed and Harrison escapes by transporting to Kronos, the Klingon homeworld.

Admiral Alexander Marcus orders the Enterprise to kill Harrison specifically with 72 sealed prototype torpedoes, with Kirk as its Captain. In his haste to avenge Pike, Kirk accepts the torpedoes without question, but chief engineer Montgomery Scott resigns in protest when Kirk denies Scott's basic request to examine the weapons for safety reasons. Pavel Chekov is promoted in his stead and Dr. Carol Wallace, a science officer who claimed to have expertise in the new weapons, joins the crew. Spock, Dr. Leonard McCoy and Uhura eventually convince Kirk that it would be better to capture and try, rather than kill, Harrison.

The landing party fly to Kronos in a confiscated civilian vessel. They attempt to capture Harrison but are intercepted by Klingons. Harrison easily dispatches the Klingons, then unexpectedly surrenders after learning the exact number of torpedoes. On the Enterprise, Harrison appears to cooperate and reveals himself as Khan, a genetically-engineered superhuman awoken by Marcus from a 300-year suspended animation.[10] With help from Wallace, each torpedo is revealed to also contain one of Khan's crew in a cryogenic pod, originally held hostage by Marcus to force Khan into developing weapons and starships to prepare for a war between the Federation and the Klingons. Eventually going rogue, Khan expects his crew would be killed in response and the attacks on Starfleet are meant as revenge. Firing the torpedoes, with Khan's crew inside, against Khan himself is intended by Marcus as a cruel punishment for Khan's transgressions. Khan also alerts Kirk to a mysterious location in the Solar System, in which a repentant Kirk asks Scott to investigate.

The Enterprise is intercepted by a larger, unmarked Federation warship, the USS Vengeance, designed by Khan and commanded by Admiral Marcus. Marcus demands that Kirk deliver Khan, but Kirk refuses. The Enterprise warps to Earth in order to report Marcus, but is attacked and crippled by the Vengeance en route, being knocked out of warp near Earth's moon. Kirk offers to exchange Khan and the cryogenic pods for the lives of his crew. Carol Wallace reveals herself to be in fact Carol Marcus, the admiral's daughter, with the mysterious torpedoes having aroused her suspicion and she spirits aboard the Enterprise following them. Admiral Marcus teleports her to Vengeance, revealing his intention to remove all evidence of his duplicity by killing everyone aboard the Enterprise and provoke a war with the Klingons by framing Kirk. The Vengeance prepares to open fire, but Scott, having discovered and infiltrated the Vengeance during his investigation, temporarily disables the weapons. With the transporters down, Kirk asks help from Khan with his insider knowledge and together, space-jump to Vengeance in order to disable it from within. In the mean time, Spock contacts his older self from another timeline on New Vulcan, and realizes Khan cannot be trusted. Indeed, after capturing the bridge, Khan overpowers Kirk, Scott and Carol Marcus, kills Admiral Marcus and seizes the Vengeance for himself.

In control of the firepower of the Vengeance, Khan demands from Spock the 72 crew in torpedoes on the Enterprise. Spock complies, but secretly removed Khan's frozen crew and armed the warheads. Afterwards, Khan mischievously transports Kirk, Scott and Carol Marcus back to the Enterprise and attacks, crippling the ship. However, the attack is disrupted when the delivered torpedoes incapacitate the Vengeance, and both damaged starships fall towards Earth. The warp-core's misalignment renders the Enterprise powerless, and Kirk sacrifices himself by entering the radioactive engine chamber to realign it, saving the ship. After Kirk and Spock confess their admiration for one another, Kirk succumbs to radiation poisoning. Grief-stricken but angry, Spock orders the Enterprise to locate Khan.

Still blaming Starfleet for his crew's apparent death, Khan crashes the Vengeance into San Francisco to destroy Starfleet's headquarters, but survives. Spock transports down in pursuit. While experimenting on a tribble, McCoy discovers that Khan's blood has regenerative properties that may save Kirk. Spock captures Khan, and Kirk is revived.

A year later, Kirk addresses a gathering memorializing the events, reciting his "where no one has gone before" speech. Khan is resealed in his cryogenic pod and stored with his crew, while Carol Marcus joins a recommissioned Enterprise as it departs on a five-year exploratory mission.

In my opinion this film is awesome and has a lot of great background characters
