Angelo never thought his dreams of a heroic journey would become a reality. When he is accidentally separated from his family, he sets off on a dangerous journey through a mysterious forest to find his way home to his sick grandmother. In this magical land, nature comes alive, and every step leads to new challenges - from fearless red ants to a moss giant. Deep in the forest, there is also the mythical Source of Life, which can save Angelo's grandmother, but on his trail is also the ruthless Ultra, the destroyer of nature, who will stop at nothing to get what he wants.
