An old plane, carrying an extremely valuable and dangerous cargo, was alleged to have crashed into Limeburners Creek near Port Macquarie, immediately following World War 11. An extensive search by many, failed to find the wreckage of this plane or its cargo. A local resident is suspected of having some knowledge of this plane crash. Her grandfather lived on the banks of Limeburners Creek and may have passed on information to her before he died. There are those who would seek to do her harm or even kill her, unless she provides relevant information. Ben Hood is hired in an attempt to stop that from happening. Ben finds himself embroiled in an old mystery which could have fatal results for him.
