A few days after his marriage to the beautiful Violet Bancroft, Sir Arthur Little is sent on a military mission to Cairo; he devotes himself to hard work and she turns to young Ronald Perry, her husband's secretary, for warmth and companionship. Violet and Ronald fall in love, and Violet, believing her position to be untenable, confesses her infatuation to Arthur and begs him to assign Ronald to another post. Arthur refuses, reminding Violet that "Caesar's wife must be above suspicion." Arthur is called away to dine with the khedive, and Violet learns that there is a plot against his life. She runs after him through the crowded streets and finds his carriage in time to prevent his assassination. Violet realizes then the depth of her love for Arthur and puts young Perry out of her mind.
