A torrential downpour suddenly strikes the city where Lin Ye lives. An unknown virus carried by the rain causes those exposed to it to mutate. They lose their reason, become irritable and aggressive, and are left with nothing but a bloodthirsty instinct. Armed with extraordinary intelligence and courage, Lin Ye begins his struggle to survive in the apocalypse.
His first love, Su Yao, has just returned from abroad. She and Lin Ye have only just reunited, and they haven't even had dinner together yet.
As the city descends into chaos, Lin Ye joins forces with Su Yao and other survivors to form a team and fight off the mutants. They search abandoned buildings for food and water, battling the creatures in a series of harrowing encounters.
During a perilous adventure, Lin Ye discovers the source of the virus: a mysterious laboratory. There, they find a way to fight the virus and learn that the disaster was no accident. It was deliberately engineered.
To save the world, Lin Ye leads his team into a decisive battle against the evil organization behind the virus. After a fierce fight, they finally destroy the organization and end the apocalyptic crisis.
But the devastation wrought by the war leaves the world barren. Lin Ye and Su Yao decide to rebuild their home alongside the other survivors. Using advanced technology and their own ingenuity, they gradually restore civilization and begin a new life.
