You play Roland Clewe, whose secret Sardis laboratory hides two unfinished machines: a submarine built to run telegraph cable under the Arctic ice, and a ray that can see straight through solid rock. With your partner Margaret Raleigh you send the submarine north under Sammy Block's command, only to learn by cipher that your rival Rovinski has smuggled himself aboard. As the sea floor rises to meet the ice overhead and Rovinski slips his watch belowdecks, the telegraph line goes dead mid-message.
