Jeremy Wade searches for more water-dwelling beasts. In this edition, he investigates people coming under attack from unseen assailants in Fiji's South Pacific paradise. Bites and deaths have been reported, but it is far from clear if there are multiple culprits or a single perpetrator. Plunging off the beaten track into the remote mountains of the island's interior, Jeremy battles intense tropical storms and unforgiving jungles in an all-out search for victims, clues and culprits. Colourful stories of monstrous fish are woven into the local folklore, but how much of this is fanciful and how much of it is real?
