The daughter of a pineapple plantation owner in Hawaii sets her sights on a married English engineer.

"Hula" Calhoun, the daughter of a Hawaiian planter, sidesteps the dissolute influence of her father through the guidance of her Uncle Edwin, who prefers a more natural existence to the society life of the family. Although Hula is adored by Harry Dehan, a boisterous rounder, she becomes infatuated with Anthony Haldane, a young English engineer who comes to supervise the construction of a dam on the estate. Haldane remains distant, however; and when saving her from a runaway horse, he informs her that he is married. At her birthday party, the broken-hearted girl turns to Dehan, and in a drunken frenzy she provokes Haldane by her dancing; he then promises to obtain a divorce, but Mrs. Haldane appears. Hula jealously bribes the foreman to dynamite a spot near the dam, convincing the wife that her husband is ruined. Haldane's wife agrees to the divorce, and he is free to marry Hula.
