John Crawford, an honest mechanic, and Wilbur Robinson, a young man of leisure, both love the same girl. She marries Crawford and a baby comes to cheer their home. Crawford is engaged in perfecting an invention and, pending the expected money, does not provide liberally for his family. The wife is dissatisfied. Robinson notes this fact and lures away the wife of the mechanic. She goes with him deserting the baby, leaving a note for her husband. They plan to leave the city, but while walking about awaiting the departure of a train, they happen to pass the doors of a moving picture theater and Mrs. Crawford expresses a desire to go in. They enter and the story thrown on the screen is identical with the experience in which they are passing through. Unable to witness the closing scenes and filled with remorse, Mrs. Crawford begs Robinson to take her out in the open. Then and there she repudiates him and, refusing to ride in an automobile, she hurries towards her humble home, hoping she may return before the husband. She reaches the house, searches feverishly for the note, finds it and destroys every vestige of her attempted perfidy. She finds the child sleeping peacefully and takes it in her arms. The husband returns triumphant. He has disposed of his invention for a sum sufficient to make them rich. The wife takes him in her arms delirious with joy and satisfaction.
