Synopsis
The Amazon rainforest is a luscious jungle wonderland, a treasure trove of many unidentified animals. The jungle is long on anecdotes about various legendary creatures, in particular the primate "Mono Grande." A photo taken in the early 20th century of this gigantic ape amazed the world as a possible new simian, and sightings remain rife today.
"Does the Mono Grande really exist?"
Driven by the desire to find out, a NHK crew thrusts deep into the jungle, encountering exotic monkeys on the way.
After over 100 days of desperate exploration, the crew finally meets up with a enormous monkey! But is it the legendary Mono Grande they are after...?
