In a post-apocalyptic world, humanity faces an unexpected and deadly threat: the carnivorous plants known as Triffids. It all begins with a meteor shower that causes a strange global blindness, leaving the majority of the population vulnerable and defenseless. Bill Masen, a botanist who has been in the hospital recovering from an attack by a Triffid, awakens amidst this chaos and realizes that the world he once knew has changed forever.
As he searches for other survivors, Bill teams up with a strong and determined woman named Susan, and together they try to find refuge in an increasingly crumbling society. The blindness has left many directionless, while the plant creatures, which can move and attack, are multiplying and rising as the new predators of the planet.
Amidst anarchy, desperation, and constant danger, Bill and Susan must fight not only against the Triffids but also against other survivors who can be both allies and enemies. With civilization on the brink of collapse, they must find the strength to confront their worst fears and seek a future in a world where human life is becoming increasingly fragile. Blending action and reflections on nature and survival, the story unfolds into an intense struggle for life, with a green backdrop filled with horror and suspense.
