Dr. Lung is an archaeologist. During a study tour in the South Pole, he discovers a frozen stone age man with his team. Unfortunately, the frozen stone age man is dropped out of the aircraft in an accident. The stone age man revives shortly. Before Dr. Lung finds him, he lives in a modern city like any other man. However, he is arrested because his primeval behavior violates the law. Is it right to use modern norms to deal with issues that the stone age man have no idea of, for he just does the ‘right’ things?
