Japan is thrown into a panic after numerous ships explode and also are sunk. Initially, the authorities believe its either undersea mines or undersea volcanic activity. The authorities quickly head to Odo Island, near where numerous of the ships were sunk. One evening, something comes onshore as well as ruins a number of residences and kills several individuals. A later expedition to the island led by paleontologist Teacher Kyôhei Yamane, his child Emiko, and young navy frogman Hideto Ogata (that also happens to be Emiko's enthusiast, even though she is betrothed to Dr. Daisuke Serizawa) soon discover something much more terrible compared to imagined in the form of a 164-foot-tall (50-meter-tall) monster whom the natives call Gojira. Currently, the monster starts a rampage that threatens to ruin not only Japan yet the rest of the globe as well. Can the beast be ruined before it is too late, and exactly what function will the mysterious Serizawa play in the fight?
