Hunt for Red October

A new technologically superior Soviet nuclear sub, the Red October, is heading the the United States coast under the command of Captian Ramius. The American government thinks Ramius is planning to attack. A lone CIA analyst has a different idea: he thinks Ramius is planning to defect, but he has only a few hours to find him and prove it. At the same time, the entire Russian naval and air commands are trying to find Ramius too.
