During his months in the Everglades, Phil Reed's imagination was captured by tales of a Spaniard's lost chest of gold. Back home, he and his friends can think of nothing else but returning to search for this treasure. When Mark Green, a friend of the Reed family, plans a trip to the 'Glades to stake out territory for a future plantation, he decides to take the boys with him as his helpers, and give them the opportunity to fulfill their dreams of finding the lost gold. But there's nothing like a search for gold to bring out the best and worst in people...and the boys find themselves in greater danger than they had expected. Will they find the gold, and if so, will the dark side of human nature ruin their best intentions?
