Ang Kalasag ng Pananampalataya (The Shield of Faith) is a documentary film about the people of San Miguel de Mayumo, Bulacan, and their centuries-old devotion to Saint Michael the Archangel. The film follows the town’s traditions—its grand fiestas, the historic Traslacion, and the music of the Biak-na-Bato Band—that continue to shape community life after 300 years. Through stories, memories, and music, the film shows how San Migueleños have carried their “shield of faith” from one generation to the next, protecting their culture and keeping their identity alive. More than history, Ang Kalasag ng Pananampalataya is a portrait of resilience and faith that invites viewers to see how tradition can endure and inspire in today’s world.
