Weeks after a recent war in the Balkans an American, Dr. Alexander Marks, visits the Balkans on holiday to visit a village from which his ancestors emigrated. While being given a tour of caves in the nearby countryside by a young woman university professor of geology, they unexpectedly stumble on a cache of poison chemicals together with the body of a near dead man who tells them that he had come to recover a treasure of gold coins from the cave and he was attacked by two men; he expires before he can tell them more. They are seen by the terrorists and pursued. They manage to elude them initially, but they find themselves in the midst a terrorist plot to poison the water supply of a nearby town. While assisting authorities to avoid a catastrophe they also explore the truth of the dying man about the hidden gold.
