This documentary follows Jay Weidner, an author, scholar, and expert in ancient mysteries, as he explores the core secrets of Western Alchemy. He investigates the ancient tradition's understanding of the apocalypse – the end of time and humanity’s profound transformation. Drawing on the writings of the enigmatic 20th-century French Alchemist Fulcanelli and a 350-year-old Alchemical Cross found in France, Weidner presents experiences, insights, and compelling evidence that reveals a new perspective on how myth, history, science, and humanity’s ultimate fate are connected. He unveils the underlying meaning of key religious and prophetic themes, including the resurrection of Christ, the Book of Revelation, Ezekiel's vision, and the Kabbalistic concept of the "Restoration of the World."
