When the Canaries Stop Singing (1992)

Overview

Canaries were used by miners to alert them to the presence of poisonous gases underground. If a canary died, they knew the air was bad. This film is about human canaries - some of the first victims of a newly recognised and devastating illness emerging in America. People are being poisoned by some of the 60,000 chemicals in everyday use. A group of chemically ill people have found refuge in unusual homes in the clean air of the small Texan town of Wimberley - with painful and bizarre results.
