In managing the shipyard inherited from her father, Derith Keogh has considerable labor problems and accedes to the unreasonable demands of John Trevelyan, an anarchist labor agitator. Derith's brother John is off in pursuit of an adventuress, and Angus Campbell, her superintendent, resigns in exasperation. Angus returns, however, to help Derith persuade Trevelyan to settle a strike, which Trevelyan accomplishes in spite of being shot by one of his own men.
