Barry Dale, the atom, a Wall Street broker, is financially ruined by his perfidious and faithless wife, and her companion, Richard Marvin, another broker, who has posed as Dale's best friend. Disheartened and depressed, Dale goes to his apartment expecting comfort and solace from his wife. Instead he finds her there in the embraces of Marvin. They laugh at him, and Marvin, the stronger of the two men, literally throws Dale out of his own home. He gives him a pistol and tells him the whole affair can best be settled, to every one's satisfaction, if Dale will kill himself. Dale walks aimlessly through the streets with this end in view. Long after midnight he finds himself on the Brooklyn Bridge, where he observes a girl about to leap into the river. A shout from Dale causes her to turn back and flee. They are mere silhouettes in the dim light, and do not see each other's faces.
