"Enterprise intercepts the energy cloud and is attacked by an alien vessel within. A probe appears on the bridge, attacks Spock and abducts the navigator, Ilia. She is replaced by a robotic replica, another probe sent by "V'Ger" to study the crew. Decker is distraught over the loss of Ilia, with whom he had a romantic history. He becomes troubled as he attempts to extract information from the doppelgänger, which has Ilia's memories and feelings buried within. Spock takes a spacewalk to the alien vessel's interior and attempts a telepathic mind meld with it. In doing so, he learns that the vessel is V'Ger itself, a living machine.
At the center of the massive ship, V'Ger is revealed to be Voyager 6, a 20th-century Earth space probe believed lost. The damaged probe was found by an alien race of living machines that interpreted its programming as instructions to learn all that can be learned, and return that information to its creator. The machines upgraded the probe to fulfill its mission, and on its journey the probe gathered so much knowledge that it achieved consciousness. Spock realizes that V'Ger lacks the ability to give itself a focus other than its original mission; having learned what it could on its journey home, it finds its existence empty and without purpose. Before transmitting all its information, V'Ger insists that the Creator come in person to finish the sequence. Realizing that the machine wants to merge with its creator, Decker offers himself to V'Ger; he merges with the Ilia probe and V'Ger, creating a new form of life that disappears into another dimension. With Earth saved, Kirk directs Enterprise out to space for future missions."
