Unai is almost always sick in bed. One day, he sees a mysterious neighbor -an old man from Ludov- coming to live in the neighborhood from the window next to the bed. After befriending him, Ludoviko will give him the key to a new world: an international language called "Esperanto". Once Unai meets the disabled boy Jua from Tanzania through Esperanto, they set off in search of the tree that is supposed to be their cure.
