The Day of the Triffids (TV Miniseries)

A terrible catastrophe has struck the population of Earth. Almost everyone on the planet has been rendered blind by the arrival of a bright comet lighting up the darkened skies, causing permanent eye damage. Bill Masen, who was unable to watch the spectacular but deadly display, finds himself in a nightmarish world where he believes himself to be the only sighted person left. As the days progress, Bill finds more and more sighted people and together they make plans to build a future. But there is a problem. A walking, carnivorous plant called a "Triffid," until now kept safely in paddocks and zoos, has broken free and has discovered a taste for rotting, human flesh.
