Esplorazioni nelle grotte del Marguereis, montagna carsica delle Apli Marittime, famosa per gli abissi e i fiumi sotterranei che la percorrono in profondità. Seguendo il filo dei ricordi d’un vecchio speleologo e l’entusiasmo di un gruppo di ragazzi avventurosi, la storia si inabissa nel mondo sotterraneo. Una ricerca che va oltre il concetto scientifico e coinvolge in forti emozioni quali la nostalgia, l’inquietudine, la febbre da esploraizone, ma anche il sollievo, la gioia del ritorno al sole.
