"The story of the shipwreck on North Sentinel Island revolves around the MV Primrose, a cargo ship that ran aground near the island in 1981. The crew initially believed it was a routine stranding, but they soon realized the danger when the indigenous Sentinelese, a fiercely isolated tribe, began appearing on the beach armed with bows and arrows. The crew was stranded on the ship for several days, defending themselves with makeshift weapons and calling for help. Eventually, they were rescued by helicopter, narrowly avoiding contact with the Sentinelese, who remain one of the most isolated groups in the world."
