Bull Kendall and his henchmen break out of a jungle prison. Bull has two goals: kill Sheena for putting him in prison and grab a jar full of gems kept in a nearby native village. Turpin, one of Bull’s fellow escapees, hypnotizes Helen, Bull’s wife, convincing her to visit a friendly fishing village as “The Queen of the Night.” When Bull & Co. dump lime into the river and kill all the fish, “The Queen” tells the tribesmen that it is the work of Sheena and natives in a nearby village. When the natives race to attack their neighbors, the bad guys, with Sheena as a captive, prepare to steal the gems.
