An astronomer of age, wealth, and erudition conducts classes in his home. His students are not always respectful, and he suffers their pranks and high jinks. Then, at noon, everything darkens and the astronomer hurries upstairs to his telescope. It is an eclipse of the sun, and through his glass, he sees a female moon coming toward a masculine sun, flirting as they move closer to what becomes a consummation. The heavens erupt with showers of stars that become women. In his excitement, the astronomer loses what little dignity he has left.

In 1970, three children are born at the height of a total eclipse. Due to the sun and moon blocking Saturn, which controls emotions, they have become heartless killers ten years later, and are able to escape detection because of their youthful and innocent facades. A boy and his teenage sister become endangered when they stumble onto the bloody truth.
