A famous bandleader, suffering from overwork and exhaustion, goes to a sanitarium for a rest. While there he dreams of being out west at a dude ranch, where he finds himself involved in the beautiful owner's struggle to keep her ranch from falling into the hands of the villain, who wants either her or her ranch (or, preferably, both).

Tommy McCoy and "Dude" Markey are both in love with Harlem singer/dancer Nita. Markey robs a jewelry store and turns the loot over to gang-boss Murray Howard. Later, Markey robs the safe, steals the jewelry, and, in order to get rid of his rival for Nita, frames the robbery on McCoy. The latter's big-brother thinks otherwise and, with Nita's help, sets out to prove it.

When American newspaperman and adventurer Henry M. Stanley comes back from the western Indian wars, his editor James Gordon Bennett sends him to Africa to find Dr. David Livingstone, the missing Scottish missionary. Stanley finds Livingstone ("Dr. Livingstone, I presume.") blissfully doling out medicine and religion to the happy natives. His story is at first disbelieved.

In the pre-Civil War South, a plantation owner dies and leaves all his possessions, including his slaves, to his young son. While the deceased treated his slaves decently, his corrupt executor abuses them unmercifully, beating them without provocation, and he is planning to sell off the father'e estate--including the slaves--at the earliest opportunity so he and his mistress can steal the money and move to France. The young boy doesn't want to sell his father's estate or break up an of the slave families, and he has to find someone to help him thwart the crooked executor's plans.
