A fleet of Martian spacecraft surrounds the world's major cities and all of humanity waits to see if the extraterrestrial visitors have, as they claim, "come in peace." U.S. President James Dale receives assurance from science professor Donald Kessler that the Martians' mission is a friendly one. But when a peaceful exchange ends in the total annihilation of the U.S. Congress, military men call for a full-scale nuclear retaliation.
Based on the Depression-era bildungsroman memoir of writer A. E. Hotchner, the film follows the story of a boy struggling to survive on his own in a hotel in St. Louis after his mother is committed to a sanatorium with tuberculosis. His father, a German immigrant and traveling salesman working for the Hamilton Watch Company, is off on long trips from which the boy cannot be certain he will return.
