Bibi and Moyo have come from the city to explore the Great Bear Rainforest. Dee, an old friend of the family is their guide. But, when their kayak goes adrift, carrying most of their things with it, they find themselves stranded in one of Earth's deepest tracts of wilderness.

What will they do for food and shelter? What if they encounter a bear? And how will they get help in this remote place without roads and without phones or radios?

Dee shows them all the tricks they need to survive, telling them all about life in this ancient forest - and why the wilderness needs to be preserved.
