The Federation Starship U.S.S. Enterprise is on routine training maneuvers when it comes up against Khan, a genetically enhanced conqueror of late 20th century Earth who has escaped his prison and has set his sights on capturing Project Genesis and destroying Kirk.
A renegade Vulcan with a startling secret hijacks the U.S.S. Enterprise in order to find a mythical planet. Kirk and his crew set out to stop a madman in an adventure that takes them to the center of the universe and, perhaps, before the face of God. With the crew under Vulcan control, the captain must rely on an unlikely alliance to save the galaxy.
Branded as fugitives by the Federation they swore to protect, the crew dutifully returns to Earth to face charges for crimes committed in the course of rescuing a resurrected Spock, but while en route, they learn that Earth is being ravaged by a strange alien probe demanding a response from a life form that no longer exists.
The first-ever dramatic miniseries to appear on American television spans decades and generations to trace the epic story of the Jordache family from 1945 to the late 1960s.
