'When 12-year-old Kim Redford and her two brothers Tony, 14 and Joe, 9, set out on a fun adventure to Flynn's Island, little do they realise the danger that awaits them. The locals say that a treasure was buried there during the goldrush days by Flynn the prospector who lived on the island with his family; and Kim has a plan to find it. But they are not alone in their quest. Also on the island are two escaped convicts who will stop at nothing to grab the gold and leave no trace behind. Luckily they bring Whisky, the family border collie, because very soon they find themselves in a life-and-death battle where only their quick thinking can save them.'
