A terrible weapon that can set off devastating earthquakes from a distance has been created, based on the scientific discoveries of Nikola Tesla, and is currently in the hands of an insane secret sect whose objective is to set off a universal war. From a secret base in Alaska, the organisation gets ready to test this powerful death instrument, and only Martin Mystère can (possibly) stop them.
