When an alien probe is threatening to destroy Earth, Admiral James T. Kirk and the brave crew of the Starship Enterprise must go back in time to retrieve one of the only known creatures who can communicate with the probe—a humpback whale.
As the space travelers try to blend in with the 1980s crowd, Captain Kirk tries to explain Spock's strange behavior to a concerned woman, saying, "Back in the '60s he was part of the free speech movement at Berkeley. I think he did a little too much LDS."
