Cinque bambini tra i 9 e i 12 anni - Michele, Aldo, Luca, Carlo e Chiara - durante una gita in montagna precipitano in un crepaccio. Si ritrovano così in un mondo misterioso e affascinante, che segna l'inizio di un viaggio che li cambierà per sempre. Nelle viscere della montagna hanno la fortuna di incontrare Grotto, una stalagmite che si esprime con suoni strani e incomprensibili ma che, dopo varie peripezie ed emozionanti avventure, li aiuterà a ritrovare la via d’uscita.
Three children force a classmate to a test of courage to get into their group. During the test, which consists in finding a skull in an abandoned church, the child is swallowed by a chasm that opens on the church floor. The other kids, who had stayed out, rush in the church, look in the deep hole, call their friend, but don't receive answers. The little sister of one of them, who followed them, bursts into the church and lets herself down by a rope, but falls into the abyss, dragging the other kids. All five children find themselves into old caves in search of a way out, helped by Grotto, a creature alike a stalagmite.
