A lunar eclipse causes a violent moonquake and releases the Gravity Goliath. Launched off the moon by the force of the moonquake, it lands on the Earth in the Pacific Ocean. The Gravity Goliath, as Brock calls it, creates a giant whirlpool that imperils the Calico and its crew.
Responding to the crew's summoning, Godzilla battles the moon monster and ultimately hurls the creature back into space, where it is recaptured by the moon’s gravity.
