Slightly Scandalous

There are two twin brothers, one of whom has three girls on a romantic string and is trying to sell a television show to a fountain pen manufacturer. The other doesn't have one girl and quietly sells insurance. The insurance seller invests money in his brother's show and, in the process of protecting his investment, gets involved with his twin's romances. Things eventually work out and the TV promoter winds up with the manufacturer's daughter and the salesman with Sheila Ryan.
