Cast & Crew
Rudolph Klein, a German spy, tries to persuade his brother Herman, a trusted employee of the Spencer Steel Works, to blow up the munitions factory. When World War I breaks out, Spencer's son Graham decides to enlist in the army, but when his mother Natalie, a cold-hearted social butterfly, objects, he wavers in his decision. Rudolph persuades Herman that Graham is trying to seduce his daughter Anna, and, for revenge, Herman finally agrees to blow up the plant. Anna overhears the conspiracy and rushes to warn the Spencers, but gets caught in the explosion instead. Her death cements Graham's resolution to enlist and he goes off to war. Natalie then decides to leave Spencer, freeing him for Audrey Valentine, a widow who has lost her son at the front.

The novel was serialized in Pictorial Review, Winter-Spring 1919. In April 1920, Eminent Authors Pictures, Inc. commenced suit for an injunction to prevent further exhibition of Dangerous Hours, produced by Thomas H. Ince and released in February 1920, because Eminent Authors claimed to have exclusive and prior right to the title Dangerous Days, and that the similarity in titles would mislead the public and benefit the Ince organization, as the novel Dangerous Days was widely known. No further information concerning the suit has been located.
