Some parts of Africa have not been explored by even the most adventurous anglers. Wars, upheavals and uncertainties have made large areas of the Nile Basin in particular too challenging and dangerous to visit. Wim Seffelaar is a teacher in daily life, but a keen angler whenever he has the chance. Over the decades he has explored some of the remotest rivers of Africa. Now he is on a quest to catch one of the most iconic and elusive of all African river fish - the legendary Nile perch. They grow to enormous proportions on a stretch of river bordering South Sudan - an area normally off limits to tourists, but with the help of local friends, Wim manages to secure the permits to allow him into this troubled area. As he follows the river searching for likely locations, he immerses himself in the tribal life along the waterways.
