The real counterfeiter, gangster Thomas Nagle and his girlfriend Norma Harrison board and with their gang take over the ship, holding the crew hostage. Shaw pretends to go along with the gang, which is running guns and counterfeit currency to Lisbon. But Shaw has no intention of letting them succeed.—Jim Beaver <[email protected]>
