A client named George Hewitt hires Joe Mannix to help find a man whom Hewitt claims has been harassing his wife, such as by accosting her in a taxicab in Chicago. Hewitt then speeds off from their meeting and is killed in a car chase with another vehicle. Mannix tries to discuss Hewitt's concerns with his widow only to find that she denies many of the things Hewitt had told Mannix -- such as never having been in Chicago, and not recognizing the man from a photograph.
