Dr. Robin Doyle returns to the jungle with her nephew Ian, a nerdy child with few friends, who spends his time collecting butterflies.

But none of this sits quite well with Jane, who worries about the dangers of a small child swinging recklessly from tree to tree -- and what Dr. Doyle will say when she finds out. (thetvdb.com)
