A young and handsome man departs from his home at his usual hour for business. As he goes on his way be is stopped and spoken to by a young and roguish-looking girl. A few words and they walk off arm-in-arm to the nearest restaurant. He tells the girl to send him a wire, making some important business appointment, so as to put his wife off the scent. The next day husband and wife are seated in the drawing-room when a telegram is brought in. Tearing open the envelope, the man reads the wire hastily, and passes it over to his wife. A glance at the urgent message, and the wife rushes off to pack her husband’s traveling bag. At the appointed place the man meets his new love and they both greet one another joyfully and dash off to the railway station. Jumping into a train, they are soon on their way to the seaside for a day’s spree. An enthusiastic and enterprising cinematographer, unfortunately for them, happens to spy them in their amusing and ridiculous love-making and immediately sets his camera and takes more copy. At home once again husband and wife are seated. It is early in the evening and the woman brings her hubby the paper and points out to him a theatrical advertisement. At the theater an apparently happy couple are seated in a box watching the pictures. All goes well until a seaside episode is thrown on the screen, and the enraged wife discovers her husband’s important engagement. Jumping out of the box onto the stage, the lady pulls her man out by the hair, and bowling him over on the stage, gives him a lesson of a lifetime.
