When the tiny nation of Freedonia goes bankrupt, its wealthy benefactor, Mrs. Teasdale (Margaret Dumont), insists that the wacky Rufus T. Firefly (Groucho Marx) become the country’s president. Sensing a weakness in leadership, the bordering nation of Sylvania sends in the spies Pinky (Harpo Marx) and Chicolini (Chico Marx) to set the stage for a revolution. As Firefly clashes with the Sylvanian ambassador (Louis Calhern), plenty of mayhem ensues, and the countries verge on all-out war.
