Stead sends Peter Thornton to a Caribbean island paradise-where he is taken prisoner! 'King' George Watt is the benign but powerful ruler of the island and if he says he doesn't want a Mogul invasion, there won't be one. He is supported by a French woman anthropologist, Dr. Yvette Leduc, who is dangerously using the islanders in a sociological experiment. She doesn't want Mogul there either, and it is she who triggers off an explosive situation by helping Peter Thornton escape.
