Nurse Betsy Conwell takes up a position on the West Indies island of St Sebastian tending Jessica, the wife of plantation owner Paul Holland, whose mind has been burned out by a tropical disease. Betsy falls in love with the melancholy Paul and seeks to help him by finding a cure for Jessica. Believing that the native witch doctors might be able to help, one night Betsy leads Jessica through the plantations to a voodoo ritual. Afterwards however, the natives become obsessed with Jessica and try to lead her back to them by voodoo. Betsy comes to realize that Jessica's condition might not be a disease, but instead caused by voodoo.
