Two hundred kilometers from the southern-most point of Africa where the water is chilly and harsh runs the Breede River. Recently, reports of a massive creature in this river have filtered through. Fish are being taken off fishermen’s lines – but only the bodies. The heads are being left intact on the line.

The picture that sends Andy off on the quest shows the head of a large Kob, one that has clearly had its body ripped off by something even larger. With shark hunter and expert fisherman Hennie Papenfuss at his side, aquatic ecologist Andy Coetzee sets out to discover the truth behind the tales and exactly what the monster could be.

While following the science and the rumors Andy embarks on a journey that follows not only the coast line of South Africa from north to south but also the sharks who are in turn following the fish.
