Summary
Highlights
Ryan and Alpha Lexa are separated from the rest of the family. They discuss the mysterious singing, which Alpha Lexa dismisses as unscientific. Meanwhile, others from their group are building shelter and gathering food, while Emma senses she's being watched.
Ryan and Alpha Lexa encounter the 'Flower Folk,' who welcome them to the island. They meet Laco, who shares that strange things have been happening on the island. Laco, Ryan, and Alpha Lexa witness a rock growing larger and larger.
Ryan's dad and Gill are saved by Laco from a falling rock. Laco reveals that Ryan and his friends might be the 'Legendary Heroes' destined to save the island, as they can hear its 'song.' They learn about a rising lava and a temple.
Ryan's team meets Koa, who explains that the island is under threat from an erupting volcano. The secret to saving the island is hidden in the temple deep within the forest. Meanwhile, another group of their family also hears the 'Help the island' song.
Emma and Kate, after hearing the island's pleas, find two ancient beings trapped. They reveal the island's dire situation: the volcano is about to erupt and only a treasure in the sacred temple can save it. They entrust Emma and Kate with a 'secret key'.
Emma and Kate send the key to Ryan via a bird. Ryan's dad uses the key to open the temple, which was hidden behind a waterfall. Inside, they discover clues about the 'Hammer of the Earth,' a treasure that created the island and can stop the eruption.
With the volcano turning red, indicating an imminent eruption, Ryan and his team navigate treacherous paths to reach the Hammer of the Earth. They retrieve the hammer just as the temple begins to crumble around them.
The entire family is reunited and learns about the Hammer of the Earth. To reach the volcano in time, Ryan, Gil, and Combo use a special turbo-boosted drone, parachuting towards the volcano.
At the volcano, they discover a large rock is blocking the magma flow, causing pressure to build. Ryan bravely uses the Hammer of the Earth to break the rock, diverting the lava and saving the island from eruption. The islanders express their gratitude.
The islanders explain that the volcano, when functioning normally, is beneficial, providing nutrients for the island's flora and fauna. With the rock removed, the volcano can bring happiness again. Ryan and his family bid farewell, promising to return.
Ryan and his family receive exclusive tickets to a mysterious island. Their excitement is short-lived as a storm hits their boat, leaving them shipwrecked on the island. Ryan wakes up to a strange voice singing, 'Save the island!'
