Chainsaw Predator

"Jeremy Wade heads to a remote river in the Australian Outback to try and catch the rare but fearsome freshwater sawfish. This shadowy predator is reputed to reach 18 feet long and attacks boats — but does the fact that it could slash Jeremy to shreds make it a killer? And why is this bizarre-looking sea monster swimming hundreds of miles inland?"

Synopsis
25 years ago, Jeremy Wade was in a hardware store in the Amazon when he came across a weapon more sinister than any he had seen before. It was a yard long and studded on each side with 2 inch long teeth. This strange weapon was the snout of a sawfish: a 20-foot relative of the rays which has been known to swim hundreds of miles upriver.

Reports claim this shark-like fish hacks boats apart and saws people in half, feasting on their flesh. Wade travels to the Fitzroy River in Western Australia in order to find out if this critically endangered creature deserves its reputation as a river monster and why it swims so far up rivers.

After being plagued by crocodiles and sharks, (which, ironically, he had previously traveled to Australia to find, yet didn't catch one for weeks) Wade hooks into this bladed beast and reels in a 7-foot monster. The episode is dedicated in memory of wildlife expert Malcolm Douglas, who died in a car accident shortly after filming.
