Immortal aliens have observed Earth for centuries, making full sensory movies of wars, natural disasters, and horrific human activities—all to relieve their endless boredom. When they finally become jaded by ordinary, run-of-the-mill tragedies, they find ways to create their own disasters, just to amuse themselves.

But interfering with human activities is forbidden, and the authorities have been known to check on these matters from time to time. However, by the time Investigator Kelexel arrives to investigate, the trouble has been going on for a long, long time—and things are really getting out of hand.
