chunk: Dr. Emil Hobbes is conducting unorthodox experiments with parasites for use in transplants. He believes that humanity has become over-rational and lost contact with its flesh and its instincts, so the effects of the alien organism he actually develops is a combination of aphrodisiac and venereal disease. Once implanted, it causes uncontrollable sexual desire in the host.
  Hobbes implants the parasites in his teen-aged mistress, who promiscuously spreads them throughout the ultra-modern apartment building outside Montreal where they live. Hobbes, unable to undo the damage he caused, kills his mistress and then commits suicide. The police are called and the crime looks to be open and shut.
