Dr. Bock, the chief of medicine at a Manhattan hospital, is suicidal after the collapse of his personal life. When an intern is found dead in a hospital bed, it appears to Bock to be a case of unforgivable malpractice. Hours later, another doctor, who happens to be responsible for another case of malpractice, is found dead. Despondent, Bock finds himself drawn to Barbara, the daughter of a comatose missionary.

Vietnam vet Jon Rubin returns to New York and rents a rundown flat in Greenwich Village. It is in this flat that he begins to film, 'Peeping Tom' style, the people in the apartment across the street. His obsession with making films leads him to fall in with a radical 'Black Power' group, which in turn leads him to carry out a bizarre act of urban terrorism.
