Godzilla vs. Biollante

In the aftermath of Godzilla's attack on Tokyo and his later imprisonment at Mt. Mihara, a team of scientists discovers cells left in the rubble by the monster and collects them. The lone assassin codenamed SSS9 steals the sample and departs. Dr. Genshiro Shiragami and his daughter, Erika, are enlisted to aid with the ambitious project. However, a terrorist bombing destroys the institute's laboratory, ruining the cells and killing Erika. Five years later, Shiragami has returned to Japan and has merged some of Erika's cells with those of a rose. He hopes to have Erika's soul continue living in the plant. Psychic Miki Saegusa, who heads an institution for intuitive children, aids him in his research. The JSDF are using the Godzilla cells they collected to create "Anti-Nuclear Energy Bacteria", hoping it can serve as a fatal weapon against Godzilla should he return. Then the creature escapes to a nearby lake, transforming to a giant plant-like being that Shiragami names Biollante. The giant gray one awakens from his hibernation to take on this most unusual enemy, a towering mutant rosebush, the result of the ill-conceived genetics experiment.
