The plot follows the novel more closely than does any other Tarzan movie. John and Alice Clayton take ship for Africa. Mutineers maroon them. After his parents die the newborn Tarzan is taken by a great Ape, Kala. Later the boy finds his father's knife and uses it to become King of Apes. Binns, the sailor who saved the Claytons and who has been held by Arab slavers for ten years, finds the young Tarzan and then heads for England to notify his kin. A scientist arrives to check out Binns' story. Tarzan, now a man, kills the native who killed Kala; when their chief is killed the black villagers appease Tarzan with gifts and prayers. The scientist's daughter Jane is carried off by a native, rescued by Tarzan (who has burnt the native village), aggressively loved by him ("Tarzan is a man, and men do not force the love of women"), and at last accepts him with open arms.

The young Gascon D'Artagnan arrives in Paris, his heart set on joining the king's Musketeers. He is taken under the wings of three of the most respected and feared Musketeers, Porthos, Aramis, and Athos. Together they fight to save France and the honor of a lady from the machinations of the powerful Cardinal Richelieu.

In the depths of the Depression, a party game brings dizzy socialite Irene Bullock to the city dump where she meets Godfrey, a derelict, and ends by hiring him as family butler. He finds the Bullocks to be the epitome of idle rich, and nutty as the proverbial fruitcake. Soon, the dramatizing Irene is in love with her 'protege'...who feels strongly that a romance between servant and employer is out of place, regardless of that servant's mysterious past...

Naive and idealistic Jefferson Smith, leader of the Boy Rangers, is appointed on a lark by the spineless governor of his state.

In Washington, however, Smith discovers many of the shortcomings of the political process as his earnest goal of a national boys' camp leads to a conflict with the state political boss, Jim Taylor. Taylor first tries to corrupt Smith and then later attempts to destroy Smith through a scandal.
