Long ago, spirits of fire and water lived as one. But jealous Algaroch, lord of the winds, drove a rift between King Oceanus and his sister Hyperia, queen of fire. Since then fire fairies and water sprites have been at war and forbidden from consorting, but when Prince Sirius, the kingÃ¢Â€Â™s chosen successor, meets HyperiaÃ¢Â€Â™s beautiful daughter Malta, they fall madly in love. Their star-crossed romance upsets golden fairy Fiale, who harbours her own secret crush on Malta, while little sea urchin Bibble bemoans SiriusÃ¢Â€Â™ absence when the undersea kingdom suffers a jellyfish attack. After Malta neglects her royal duty to protect the Holy Flame, their secret comes out. Slimy sea serpent Mugwamp the Magnificent, who covets SiriusÃ¢Â€Â™ throne, seizes his chance and sets the young lovers fleeing their vengeful parents. A wise, old turtle explains their one chance is to reach the hill of Elysium during the next solar eclipse, where a magic flower blossoms that can carry them to a distant star where fire and water live as one.
