An island… a treasure

An old letter, a shipwreck, the lost treasure of the « Indian », talking rocks, a wind full of goodwill but who ends up getting angry ... very strange things happen on this small island. Things that will lead Lulu and Lili, our little heroines, to open their eyes to the real treasure of the world and to the importance of daily actions of each individual. But it's true anyway, "Only kids are prepared to listen to talking rocks.. and hear what they say".
