The White Flower (1923)

"You'll see Betty riding the surf at the famous beach at Waikiki, and dancing the Hula-Hula!"

Konia Markham, the daughter of an American father and a Hawaiian mother, is told by a sorceress that the man who presents her with a perfect white flower will be her true love. When Bob Rutherford offers a gardenia to Konia at a banquet, David Panuahi, a rejected suitor, becomes even more jealous and persuades Konia to have the kahuna put a death curse on Bob's fiancee, Ethel Granville. Bob's devotion to a failing Ethel softens Konia, however, and she has the curse removed. She is about to jump into a volcano when Bob, now released by Ethel from their engagement, finds her and declares his love.
