Young Helen Keller, blind, deaf, and mute since infancy, is in danger of being sent to an institution. Her inability to communicate has left her frustrated and violent. In desperation, her parents seek help from the Perkins Institute, which sends them a "half-blind Yankee schoolgirl" named Annie Sullivan to tutor their daughter. Through persistence and love, and sheer stubbornness, Annie breaks through Helen's walls of silence and darkness and teaches her to communicate.

A French convict in the 1930s befriends a fellow criminal as the two of them begin serving their sentence in the South American penal colony on Devil's Island, which inspires the man to plot his escape.
