A Pair of Cupids (1918)

Henry Burgess favors a match between his ward, Virginia Parke, and his nephew, Peter Warburton, but she is only interested in her poodle, Frou Frou, and Peter devotes all of his attention to his business. To bring them together, Uncle Henry rents twin babies of the laundrywoman, Bridget McGroghan, placing one on Peter's doorstep and the other on Virginia's. Each discovering that the other has a baby, Peter and Virginia soon begin to share their views on child rearing and matrimony, and are about to become engaged when the babies disappear. Michael McGroghan, the twins' father, hires a pair of crooks to kidnap the babies so that he may collect the $25,000 bond that has been put up by Henry for their safe return. Peter, however, tracks down the kidnappers, and after the infants are returned to their grateful mother, he and Virginia look forward to having their own babies. (from the AFI)
