John Grant, capitalist, is devoted to his wife, but is obliged to curtail her weekly allowance because of her fondness for cards. Robert Baker, a wealthy bachelor, is a great admirer of Mrs. Grant and calls frequently. Finding that her allowance is not enough for her losses at cards, Mrs. Grant, incited by society friends, deceives her husband in the hope of gaining more pocket money. Mrs. Grant loses a hundred dollars at cards, and she gives her I.O.U. to Mrs. Condon, the hostess.
