The Hunt for Red October (1990)

A new, technologically-superior Soviet submarine, the Red October, is heading for the U.S. coast under the command of Captain Marko Ramius (Sir Sean Connery). The U.S. government thinks Ramius is planning to attack. C.I.A. analyst Jack Ryan (Alec Baldwin) has a different idea. He thinks Ramius is planning to defect, but he has only a few hours to find him and prove it, because the entire Russian Naval and Air commands are also trying to find him.
