Four young men went into the jungle on the adventure of a lifetime.
Only two of them would come out alive.
The Amazon rainforest is roughly the size of Europe or
Australia. It is the home of more than half the plant and
animal species known to man, many of which are lethal.
In 1981 three friends went backpacking in a remote
area of Bolivia: Yossi Ghinsberg, 22, and his two friends
Kevin Wallace, 29, and Marcus Stamm, 29. They hired
an experienced guide, an Austrian called Karl, who
promised that he could take them deep into the rainforest
to an undiscovered Indian village. Then they would raft
nearly 200 kilometres back down river. Karl said that the
journey to the village would take them about seven days.
Before they entered the jungle, the three friends made
a promise that they would 'go in together and come out
together'.
