A Traveler's Aid worker who delights in solving people's problems gets mixed up with gangsters.

Lynn Palmer, a worker with the Travelers' Aid Society in San Francisco, is asked to share her apartment with Velma Tuthill, a socialite whose mother has donated a great deal of money to the Society. Velma is only interested in the job because it provides a way to meet her boyfriend without her mother's knowledge. Engineer Mack Hale meets both women when he comes to the Travelers' Aid station in search of his best steel worker, Stanislaus Janauschek. Although Velma flirts with Mack, he and Lynn recognize each other as childhood sweethearts and make a date for that evening. Mack, who is superintendent of the Golden Gate Bridge project, is threatened by Sharkey, a racketeer who demands protection money. When Mack refuses, Sharkey pays some of the workers to get their crew drunk while they are on the job. As a result, one of the drunken men falls to his death and Mack fires all the men who were drinking. Meanwhile, Mack and Lynn fall in love, but quarrel when she refuses to give up her job to marry him. Lynn learns that the bridge workers plan to hold a strike meeting to get rid of Mack and when he will not attend to defend himself, she faces the workers alone. At the last minute, Mack finds a worker who tells the others the truth about Sharkey and the strike is averted. Mack now understands the value of Lynn's work and they are reunited.
