A Norwegian scientist (John McCallum) invents a machine that converts sound to energy but is then stolen by his wife (Mary Laura Wood) who travels across the snowy regions towards Russia. She is pursued by policeman Jack Warner, her husband and a local woman (Nadia Gray). Jack Warner was good as a London character, but not convincing as a Norwegian detective. The acting and direction is at best average, but the shots of the herds of reindeer and the eagles attacking the wolves are impressive.
