Dr. Jane Tiptree has withdrawn from public life to conduct sequestered research for the Eunice Corporation. The DARPA is wary of her work with genetically modified chickens but cannot legally interfere in her research. While in transport, one of Tiptree's chickens hatches a reptilian creature which kills the driver and escapes. Meanwhile, near her laboratory in the small town of Climax, Nevada, the populace begin suffering from a mysterious illness with flu-like symptoms.
