EDGE OF EXISTENCE
by Tigress Productions of UK.

The Insect Tribe of Papua New Guinea were unknown to the outside world until 50 years ago and have a reputation as fearless crocodile hunters.  Donal joins the warriors on a terrifying night-time hunt in dugout canoes, where the tribesmen think nothing of spearing crocodiles as big as their canoes.  The tribe still uses seashells for money, but things are changing fast as the 21st century encroaches on their lives.
