In 1877, Tahiti secretly plans to revolt against France, aided by British gun-runners who are no match for police commissioner Duvois. Now, prosperous American Mike Macklin is persuaded by Queen Pomare to help. As an excuse for sailing to San Francisco, he must enlist a "wife" of convenience; enter gold-digging showgirl Wanda Spence. Will Mike tame her or ignore her in favor of inauthentic dancer Mawaii? A hurricane's brewing, the natives are restless...and so is the volcano!
