A race against time. The "Lords" from the planet Sark oppress the inhabitants of the planet Florina, an agricultural world. There, Kyrt is produced, a fluorescent fiber that cannot be manufactured anywhere else in the universe. When a space analyst from Earth discovers that Florina's sun is about to become a supernova, he becomes a threat to the "Lords." They transform him into a helpless idiot with a psychosonic probe and abandon him on Florina. However, after a year, his memory returns, and he begins to search for the origins of his seemingly irrational fears.
