In the South Seas, half-caste Ilanu (Raquel Torres) refuses to marry Kahea (Donald Reed), as she loves Jimmy Bradford (Ben Lyon), heir to an American fortune; her grandfather warns her that her own mother's marriage to a white man was so unhappy that she'd leaped into a volcano. Despite misgivings over her race, and lingering feelings for his previous fiancee Elaine (Marian Douglas), Jimmy does marry Ilanu and takes her to San Francisco with him. His father (Robert Edeson) and sister Winnie (Thelma Todd) are shocked by Ilanu's apparent vulgarity, but Jimmy remains loyal to Ilanu, even though this means they return to her island, penniless. ~ Bill Warren, Rovi
