After plundering and desecrating a temple in India in 1913, drunken archeologist John Prendergast is cursed by the priest, who re-animates a gorilla Prendergast killed and orders it to wreak its revenge on the thief. Twenty years later, a partially paralyzed Prendergast resurfaces in the United States as the rich philanthropist, John Pren. His backers assemble at his mansion to demand their share of his plunder. Pren warns them that the "spirit of Kali" (the undead gorilla) killed two people he tried to repay. A
séance is held to try to contact and appease Kali, but one of the backers is found strangled afterward. Later that night, another backer is found dead, dressed in a gorilla suit. A police investigation goes nowhere, and backer Jack Armstrong is attacked by the gorilla but escapes. Another backer dies, and Pren is found unconscious—the ape's attack on him apparently interrupted. Pren proposes to his nurse, Ella, which enrages Pren's long-time companion, the Hindu girl Chanda. The police discover Pren has been faking paralysis and has been killing off his backers by allowing Kali to attack them. The ape kills Pren, but the police save Ella in the nick of time. ==Cast==
