Japan is being ravaged by bizarre and powerful giant monsters. A reptilian creature called Baragon is creating earthquakes in an oil refinery, Rodan is leaving sonic booms in his wake, a hideous blob of slime called Hedorah is feeding off of the city's toxic waste and growing larger every second, a giant caterpillar named Mothra is laying eggs in different parts of town,, and Godzilla is plowing through everything around him. Only the Allied Defense Forces can stop them. (wiki)
