In a frontier mining settlement, two young men set out from the diggings and fail to return. Their horse, riderless and in distress, eventually makes it back to town, raising alarm. A search party is organized, including a trooper and a seasoned miner, to track down what happened. Their journey leads them through rough bushland, past ominous terrain, toward a ravine known as Bluemansdyke, where the clues begin to reveal a darker mystery. Suspense builds as the party follows trails, uncovers signs of wrongdoing, and edges closer to confronting the unknown forces at play.
