Along the wild Namibian coastline, where the Atlantic crushes against ancient desert, a silent crisis unfolds. Thousands of "Cape fur seals" are fighting a deadly and ever-growing threat: marine debris. Ghost nets, fishing lines and plastic waste drift silently through the ocean, ensnaring thousands of animals each year. UNSEEN LINE follows the work of Ocean Conservation Namibia (OCN), a small but fiercely dedicated NGO founded by Naude and Katja Dreyer. What began as a spontaneous rescue of a single seal has evolved into a full-time mission: a race against the increasing tide of ocean waste.
