Ah Kai is a wanted convict from Hong Kong who escapes to South Africa after killing his former boss and his boss's wife. In South Africa, he works at a Chinese restaurant and one day travels with his boss to a South African tribe that is infected with the Ebola virus. Kai sees a dying infected tribe member and rapes her, contracting the virus. Kai, however, is immune to the infection. He becomes a living carrier, spreading the disease to others through body fluids. He ends up killing his new boss and his boss's wife, but not before spreading the virus to them. He then cuts up their corpses and serves them as hamburgers in the restaurant, effectively spreading the virus all over South Africa. He then further spreads the virus when he flees back to Hong Kong, to all the people he has contacts with.
