The film is about an extraterrestrial (played by Brad Dourif) who came to Earth several years ago from a water planet (The Wild Blue Yonder), after it suffered through an ice age. His narration reveals that the aliens have tried through the years to form a community on our planet, though without great success.
The alien also tells the story of a space mission he became aware of after finding a job with the CIA. In the late 90s, he says, the debris from the Roswell UFO crash was unearthed and examined. The scientists falsely believed that they had contracted an infectious alien disease from the debris, and an exploratory mission was launched to Blue Yonder (represented with archival footage from STS-34 and Henry Kaiser's diving expedition in Antarctica) in order that a new, uninfected human colony might be created there. After deciding Blue Yonder was suitable for human habitation, the astronauts returned home to Earth 800 years later only to discover that the planet had been abandoned in their absence.
