The main characters of these six stories, Roscoe, Simione and Dan-Dan, are 12 year old triplet brothers who live in rural New Zealand. A forest park and coastal waters are their playground, an environment that has taught them survival skills and tests them to their limits. The special bond between the brothers is an all important ingredient in their adventures. A mysterious person appears in all six stories, a figure who the boys doubt they even saw at all.

Story five, The Cave: On holiday at the top of the South Island, the triplet brothers discover fossils in a limestone cave. Exciting discoveries are made but unexpected natural forces have tragic results. A chance meeting with Katrina proves to be a life saver, and their friendship has a brand new start.
