Star Trek IV: The Voyage Home

Synopsis

Following the events of their previous mission, Admiral James T. Kirk and his loyal crew are returning to Earth in a hijacked Klingon Bird-of-Prey to face court-martial for their insubordinate actions. However, their homecoming is interrupted when a massive, enigmatic alien probe positions itself over Earth, vaporizing the oceans and disabling the global power grid in a futile attempt to communicate with the extinct humpback whale species. Realizing that humanity faces total annihilation, Kirk and his crew formulate a desperate plan to slingshot around the sun, executing a dangerous time-travel maneuver back to late twentieth-century San Francisco. Navigating the bizarre cultural landscapes of 1986, the crew must secretly track down a breeding pair of humpback whales, build a makeshift tank inside their cloaked vessel, and safely return to the future to save their planet. Directed by Leonard Nimoy, this lighthearted, eco-conscious entry stands out as one of the most commercially successful and widely accessible chapters in the original Star Trek franchise.
