River Monsters - Season 1 - Eps 5: Amazon Assassins
In the darkest depths of the Amazon lurks a dinosaur. Legends tell of an evil spirit inhabiting an enormous fish. Taller than a man, it is covered in scales and crushes its prey with a tongue made of bone. Jeremy Wade has encountered this creature once before, and he came out second best. He's taking no chances in the rematch.
