Introduced by Caroline Jones.

It was supposed to be the adventure of a lifetime but when Australian nurse Christy King led a group of experienced trekkers into the PNG jungle everything changed in an instant.

Early in the evening of their first night in the mountainous terrain of the Black Cat track, the group was attacked by men wielding machetes and robbed at gunpoint.

As day turned to night, Christy King was left to decide how best to protect the men in her care and how to manage the serious wounds of the PNG porters who took the brunt of the attack.

With two of her group already dead she was left to make difficult and unenviable decisions.

For the first time, she speaks publicly about the ordeal.
