A Destemida Diana

David Sheldon owns a plantation in the Solomon Islands. Many of his field hands die of blackwater fever, and then he becomes sick himself. Joan Lackland, a female soldier of fortune, arrives by schooner in the islands. With the help of her Kanaka crew, she protects David from an attack by the natives who are led by Googomy. Joan nurses David back to health and becomes his business partner, protecting his mortgaged property from two avaricious moneylenders. Seeking vengeance, the moneylenders incite the natives to revolt.
