Among the mountain gorillas of Rwanda, Titus reigns as king with extraordinary courage, strategy and determination. The record of his life began when Dian Fossey, the famed primatologist, introduced a young researcher named Kelly Stewart to the gorillas. Stewart was there to make the very first journal entry about young Titus, meeting and naming him in 1974, when he was just a tiny baby. In the following decades, he was orphaned, survived poachers, and overcame the deadly challenges of his rivals. His triumphant story is recounted by researchers and conservationists as they share their memories and archival footage of Titus.
