Admiral James Kirk of the Starship Enterprise is on the planet Vulcan, commanding his recently seized Klingon Bird of Prey and picking up Spock so they can go back to Earth to face charges for their crimes. However, life on Earth is not the best. A powerful alien probe has appeared out of nowhere and nobody knows what language it is speaking in . . . or more importantly, whom they wish to commune with. When they set Standard Orbit around Earth the oceans are being steadily vaporized; Spock figures out that the probe is calling to humpback whales. Problem is they have been extinct for the past two centuries!!!! Kirk and his crew 'Time Warp' from the 23rd to the "primitive and paranoid" 20th century. Along the way, they run into a marine biologist who is a bit protective of her two whales, George and Gracie. Also, the crew run into some 'technical' problems.
