Jack learns that Scott-Palliser is planning to have him arrested for gun-running. He sends Tania home and gets the ship's captain to put ashore elsewhere to avoid the Nationalist gunboat, taking loyal ship's steward Raoul Savory with him. Jessie is shocked to discover that Scott-Palliser has been financed by Stalin's government and plans to give the guns to the Communists and not the Socialists, whom he sees as traitors.
