Inspired by true events, Mallari tells the horrific story of Fr. Severino Mallari, a 19th century priest during the Spanish occupation and his descent into madness. The film recounts Father Mallari’s life and work as a parish priest in Pampanga, where he reportedly murdered 57 people to aid his ailing mother.
