Godzilla has fallen into a volcano, and Tokyo begins rebuilding following his onslaught. In the debris a research team discovers a chunk of Godzilla cells. But they are spirited away by a mercenary who delivers them to the Republic of Saradia. There, Dr. Shirigami plans on using the cells to create grains that can grow in harsher environments. A terrorist explosion at the lab destroys his hopes and kills his daughter.
Five years later, Shirigami is studying plant biology in Japan, believing the spirit of his daughter is in the roses. He is being assisted by Miki Saegusa, a clairvoyant. The Special Disaster Research Council- Godzilla Unit takes Miki on a helicopter tour over the volcano, who declares Godzilla is awake. A project is launched to create an Anti Nuclear Energy Bacteria, which would essentially eat nuclear material in the event of an accident. But they need some Godzilla cells. Shirigami agrees to help.
Rival biotechnology firm Bio Major sends a pair of thieves to break into Shirigami’s lab. They are interrupted by the mercenary from Saradia, who is also seeking to steal secrets. All three men are attacked by long, ropey strands that pull them away, but the mercenary is able to slip away. The creature disappears.
Bio Major demands the research on the bacteria, or it will set of explosives around the volcano containing Godzilla, causing his return. The Japanese government concedes.
At a lake near Shirigami’s lab, a creature rises. The giant stands on a thick tree-trunk like stalk, with long vines for arms, and is topped with a rose. Shirigami reveals he developed Biollante with Godzilla, plant cells, and DNA from his dead daughter.
Asuka and Sho meet a Bio Major agent to deliver several samples of the bacteria from Shirigami’s development, but are ambused by the Saradian assassin. The Bio Major agent tries to flee in a truck, but is killed by the Saradian, who takes the case containing the bacteria. Asuka and Sho are unable to stop the explosions on time and Godzilla rises from the volcano.
The Japanese Defense Force meets the King of the Monsters in the Pacific Ocean, and greets him with a barrage of canon fire and missiles. He destroys them without batting an eye. A newly rebuilt, more powerful Super-X is deployed against the advancing beast. It is able to reflect the nuclear blasts back to Godzilla. He retreats for a while, but Biollante calls out to him. Godzilla damages the Super-X and continues his path to Biollante.
The two monsters battle in the lake, with Biollante tying up Godzilla in its tendrils. Godzilla struggles against the bonds and unleashes a nuclear blast at Biollante that cuts like a scalpel and explodes the rose-head. Miki, who can still sense the bio-engineered creature, reports Biollante is dying. But in the inferno, Biollante releases pollen. Godzilla disappears into the ocean.
Miki is engaged by the military to find Godzilla, and finds him while in a helicopter. He appears to be headed to a nuclear power plant. A repaired Super-X is dispatched against the monster. With the Japanese Defense Force lying in wait at the power plant, Godzilla surfaces miles away at Osaka Bay. Using her ESPer powers, Miki attempts to contact Godzilla and delay his entry into Osaka.
Asuka and Sho snatch the Anti Nuclear Energy Bacteria from the Saradian business offices, just before Godzilla comes ashore. The King of the Monsters stomps through Osaka, leaving fire and destruction in his wake. The Super-X launches a barrage of missiles at Godzilla, but it only enrages the beast and he again destroys the Super-X. In several nearby buildings a team lead by Asuka and Sho use bazookas to fire the bacteria at Godzilla. Godzilla leaves, but the bacteria doesn’t seem to be working. His body temperature is too low to allow its growth. A plan is hatched to raise his temperature by using giant microwaves. Even that doesn’t work. It appears Godzilla is immune to the bacteria.
From out of the rain clouds, Biollante’s pollen falls, and a new hybrid creature rises from the ground. It is bulkier, and has more vines. Instead of a rose, Biollante’s head is more similar to Godzilla’s, only with a longer snout, with the vines ending in Venus Flytrap-like mouths. It advances toward Godzilla and stabs him in the shoulder and hands with its new blade-like tendrils. The two grapple. Godzilla stumbles away and falls into the ocean. The bacteria finally appears to have worked. Biollante disintegrates into a cloud of pollen, and Shirigami sees an image of his daughter in the rising pollen.
As he calls out to his daughter, Shirigami is shot and killed by the Saradian assassin. As he escapes, he steps into the microwave zone and is vaporized. Godzilla rises again. The water has lowered his body temperature, inhibiting the growth of the bacteria again. He heads off to sea.
