Danae, a woman who came from the sea is a beautiful blonde girl at the center of a spy story during the second world war. In Gibraltar, Italian and British divers perform mutual sabotage actions. The secret agents, on the other hand, face off on the mainland and the Italian spies have the best thanks to the girl's intervention.
