She convinces her cousin Adele--who is actually also in love with Jim--to get him to propose. Jim's sight returns and he and Helen marry, but on the day their child is to be born, he goes blind again. Frustrated by being married to a blind man, Helen falls in love with his assistant Jean Du Bray. Complications ensue.
