After Ruth complains to her superintendent about undernourished schoolchildren, Minski's ravings cause her suspension, and she joins the Reds. Meanwhile, Captain Nathan Levison, returning from the Argonne, is assigned by the Secret Service to investigate New York's radicals.

Smith signs a bill making it illegal to display the Red flag, the Bolshevists plot to assassinate him, the Mayor of Seattle, and Attorney General Alexander Palmer, but Davy, with other soldiers, break up the meeting.
