When International Projects Corporation's president, Edward L. McKeever (Paul Douglas), resigns to take a government job, the probing questions of small stockholder Laura Partridge (Judy Holliday) so embarrass the new Board of Directors that they put her on the payroll. As the new Director of Stockholder Relations, Laura's letters win her countless allies who help her expose shocking examples of executive mismanagement. Though Laura persuades McKeever to return to the company, his having surrendered his stock when he took the Washington job leaves them both with little influence. However, empowered with the proxies of the company's many small stockholders, Laura routs the dishonest board. And when McKeever takes over, she becomes his vice-president, secretary -- and bride.
