Nine-year-old Tyler has a dream life. His family's ocean-side marine life park is all he's ever known and the sea animals his closest friends. But when developers threaten to buy out the park due to its fading attendance and dwindling finances, he plots with his cousin, nine-year-old Aaron, to find a buried treasure rumored to exist somewhere on the property. A treasure buried centuries ago by one of their ancestors, the notorious pirate, Blackbeard. Hanging on the park's restaurant wall is a treasured family heirloom map which supposedly pinpoints the location of the treasure, but critical information is missing due to a lost torn corner of the map. Then, items discovered in a family trunk of heirlooms provide more clues for the cousins as do the mumblings and puzzles of a couple of the small town's oldest citizens. When mysterious events take place to thwart the search and bring down the demise of the old theme park, the boys realize someone else believes in the stories of gold and silver. Does the treasure really exist and if so, will they be able to find it in time to save the park?
