The local economy in his small town threatened by the arrival of a massive new shopping center, a 12-year-old boy attempts to save his family home by hunting for lost treasure with his mischievous golden retriever Marley, and a young girl who isn't afraid of a big challenge. Josh Peters was having the perfect summer until he learned that his family could soon lose their home. A new shopping center is about to be constructed, and it's sure to drive his father's store straight into the ground. Is there any hope for keeping their small town alive? Legend has it that the Conquistadors once left a sizable treasure in the area, and when Marley digs up a golden medallion with a map to the riches, Josh and spunky town newcomer Ana set out to recover the gold and save their town. But the kids aren't the only one with visions of gold coins spinning in their heads, because dimwitted fugitives Wade and Scarecrow are determined to claim the treasure first. Now, in order to thwart the dastardly duo and find the hidden treasure, Josh, Ana, and Marley must stay one step ahead of the hoodlums while navigating a treacherous forest, avoiding an array of elaborate booby traps, and descending into a darkened cavern in search of endless riches.
