Brief Description  Released on May 12, 1963, The Day of the Triffids is a British science-fiction horror film directed by Steve Sekely and an uncredited Freddie Francis. Loosely based on John Wyndham's 1951 novel, the film follows merchant navy officer Bill Masen (Howard Keel) as he navigates a world where a spectacular meteor shower blinds 99% of humanity, allowing ambulatory, venomous, man-eating alien plants to conquer civilization.

Plot:
The story begins with a bright, beautiful meteor shower in the night sky. Most people go outside to watch the colorful lights. The bright glow permanently blinds about 99 percent of the human population on Earth. The main hero is an American sailor named Bill Masen. Bill is in a hospital in England with his eyes bandaged after a medical operation. Because his eyes are covered, the bright meteor light does not hurt his sight. When Bill takes off his bandages the next day, he finds a broken world. Planes have crashed, fires burn out of control, and blind people wander the streets in a helpless daze. Some blind survivors act desperate and swarm anyone who can still see.

The meteor shower also brings alien spores to Earth. These spores grow very fast into Triffids—tall, aggressive plants that can pull their roots from the ground and walk. Triffids have a deadly sting and hunt humans and animals for food. They are also attracted to loud noises. Bill meets a woman named Christine and tries to find a safe place. They travel through England and try to reach a military base in France for help. The movie features a separate side story. A married couple—an alcoholic scientist named Tom Goodwin and his wife Karen—are trapped inside a remote lighthouse in Cornwall. They fight off attacking Triffids while trying to survive. Tom discovers a major weakness. He realizes that salt water dissolves the Triffids and makes them melt. The survivors use sea water to defeat the aggressive plants and save humanity.
