Every year, thousands of Shia gather in the small town of Nabatiyyeh, Lebanon, to commemorate the death of Imam Hussein, killed in battle 1433 years ago. They proceed to very long processions, flagellation and self-mutilation, and thrive to reenact the martyrdom of Imam Hussein with their own blood and flesh. MYSTIC MASS documents the ceremony, and provides an exhaustive description of how the mass is formed, how it attains its highest mystical levels, and how it dissolves - all within 24h.
