The Scrapper plot
Malloy, a young Irish construction engineer fresh out of college, is assigned a project and immediately falls in love with the contractor's daughter, Eileen. The contractor's secretary, who also loves the girl, hires Oleson, a Swede, to work with Malloy and delay the construction enough to incur the contractor's wrath. Under these circumstances, however, Malloy works all the harder, never looking gloomy or restraining his Irish humor until the Swede clashes with him over a strike. Having proven himself, he takes Eileen to the priest, and her resistance is overcome.
