 A greedy developer has placed huge machines to suck dry a part of the ocean near Tokyo so he can put luxury condos there. After a storm, a giant egg washes up on the beach nearby and is immediately put on public display. The developer s plans go awry when he disrupts Godzilla s rest and the monster goes stomping through Tokyo again. It s up to the elderly Mothra, and then to its two offspring, to save Tokyo from destruction.
