In 1954, Godzilla, a prehistoric alpha predator, is lured to Bikini Atoll in an attempt to kill him with a nuclear bomb. In 1999, Monarch scientists Ishiro Serizawa and Vivienne Graham investigate the skeleton of a monster similar to Godzilla in a cavern unearthed by a collapsed uranium mine in the Philippines. They also find two giant spores, one dormant and one hatched, along with a trail leading to the sea. In Japan, the Janjira Nuclear Power Plant experiences unusual seismic activity as supervisor Joe Brody sends his wife Sandra to lead a team of technicians into the reactor. A tremor breaches the reactor, forcing Joe to close the reactor door before Sandra and her team can escape while the plant collapses.
