Aboard a submarine of the ancient kingdom of Mu, Martin Mystère and Java are prisoners of Robinson, an android programmed to wage eternal war on the terrestrials, whom he identifies as the descendents of the people of Atlantis. However, our prisoners acquire a secret ally, Mara Marata, once on Robinson’s side, but now conscious of the terrible menace the android represents for the whole of mankind!
