Lillian Travers, a New York heiress, pops down to Florida to surprise her fiance, Fred Cassadene, the house doctor at a prominent summer and winter hotel. The surprise, however, is Lillian's when she finds Fred in a series of compromising situations with a certain wealthy widow staying there. When she can take no more, Lillian discovers a box forgotten at an old curiosity shop in which lies a hundred year old secret: a vial of four rare and exotic African seeds that promises to transform whoever swallows one from a woman to a man or vice versa.
