Matteo, a boy from the city, goes to visit his grandfather in a secluded mountain village, where preparations for a local ancient festival are under way. Matteo spends the eve of the festival with Lidia and three other boys from the village. The group of kids begins a dangerous game, bringing up obscure mysteries that are rooted in the past of that mountain valley. Matteo thus goes through a sort of initiation, at the end of which he is able to exorcise his fears, but only after becoming uncomfortably conscious of the existence of evil.

Matteo, a városi fiú a nagymamáját látogatja meg abban az elszigetelt kis hegyi faluban, melynek lakói épp egy ősi fesztiválra készülődnek. Matteo a falusi gyerekek társaságában vesz részt az ünnepségen, és miközben a többiek veszélyes játékot űznek azzal, hogy réges-régi titkokat fednek fel a hegyi völgyről, Matteo is egyfajta beavatási szertartáson esik át, melynek végén talán szembesülhet saját félelmeivel.
