Millions of years prior, a giant three-headed space dragon called Desghidorah arrives on Earth and battles a species of enormous and highly advanced moths who serve as protectors of the "Elias", a race of tiny, humanoid beings.

After the battle, Desghidorah is defeated and sealed under the Earth while three Elias, the benevolent Moll and Lora and the vengeful Belvera, and one moth, Mothra, remain.

In the present, as Mothra exhausts energy to lay an egg and preserve her species, a logging company uncovers Desghidorah's subterranean prison and inadvertently break the seal containing it.

Taking advantage, Belvera, believing humans are the enemy, controls Wakaba, and makes her torture her brother Taiki.

Moll and Lora befriend Taiki, Wakaba, and their mom and they all travel to the site containing the seal in hopes of stopping Belvera.

While Taiki and Wakaba are witnessing the destruction left in the wake of the monster, Moll and Lora encourage them not to lose hope.

Drawing upon an ancient legacy, Mothra eventually renews the seal that originally bound the dragon, defeating him, and saving Earth.

[6] A triple feature of all three Rebirth of Mothra films was released on Blu-ray by Sony Pictures Home Entertainment on September 9, 2014 with both the Japanese and English voice tracks.
