The legendary jewel known as the "Flame Goddess" is said to grant immense power to its bearer. To protect this jewel, investigator Ran Ousaki is attacked by the evil monster Gorgona's gang. Swallowing the gem, she gains the power to transform. Using this power, Ran transforms into Garuda and subjects Gorgona's henchmen to sexual torture to extract information about their hideout. Eventually, the battle to defeat Gorgona begins. After claiming victory, Garuda gives in to her rising excitement and takes further action.
