"Julie Ridgehaven, of Sydney, Australia, while attending college in California, receives a cablegram asking her to fly home at once due to an emergency in the family. Her friend Betz Condon accompanies Julie. During a stopover in Fiji, Dan Fargo, a friend of Grandfather Ridgehaven, boards the plane, and Julie learns that her fiancé Ron McLaren is lost in the bush. Grandfather arranges an expedition to search for Ron, and Julie and Betz are members of the party. Julie observes that her cousin Wally Ridgehaven is very much interested in Betz, and her Aunt Isabelle is increasingly apprehensive over the prospect of a meeting with Dr. George whom she had once promised to marry."
