Derith Keogh (Claire Windsor) inherits her father's West-coast shipyard when the old man dies. Angus Campbell (Rockcliffe Fellows), her adoptive brother, is in love with her but too shy to reveal his feelings. Angus stands up to renegade labor-leader John Trevelyan (Thomas Holding), who incites worker unrest, and Angus and Derith avoid a labor strike when they assure John of his value as an employee. Derith finds out that her heroic adoptive brother loves her and proposes marriage. Angus accepts after explaining he did not wish to appear an unscrupulous social climber by revealing his love for her.
