Afer being stabbed with an ancient, germ-infested knife, a doctor's assistant finds himself with an insatiable desire for blood.

A New York anthropologist, Dr. Hess Green, is embroiled in a study of the lost ancient African culture of Myrthia, a nation that died out due to a communicable parasite that fed on human blood. During his research, Dr. Green is stabbed with a jewel-encrusted Myrthian dagger by his crazed assistant and finds that he has become infected with the virus, turning him into a vampire-like creature who is addicted to blood and fancies himself an invincible African God; and who turns his wife, Ganga, into a vampire as well.
