After making his wife a present of a new striped bathing suit, Mr. Peters is astonished to see the suit in the sea in the arms of a strange gentleman. Peters, on the sand, storms and rages at the couple out in the water, but they do not seem to see him. The gentleman bestows a kiss and this is the last straw. Peters wades out in his best suit of clothes to get at the fellow. When the water reaches his chin the lady faces him and to Peters' surprise it is not his wife at all, but another young lady who has purchased a striped bathing suit at a department store.
