Four childhood friends made a pact: every year, they reunite in their small hometown in Puglia. Art, the magnetic leader of their group, insisted that the tradition must never be broken. But this year, Art doesn’t show up.
Worried, they visit his home—and what they find raises more questions than answers. Art has been growing marijuana, a dangerous gamble in Southern Italy. Worse still, the town is buzzing with rumors: some claim Art miraculously cured the local mafia boss’s daughter of leukemia.
Among the chaos of his house, they discover The Book of Hidden Things, a manuscript written by Art, promising to reveal dark secrets and unimaginable wonders. As they dig deeper, the line between reality and the impossible begins to blur.
