chunk: As Dr. Bock complains of impotence and has thoughts of suicide, he falls for Barbara Drummond (Diana Rigg), a patient's daughter who came with her father from Mexico for his treatment. This temporarily gives Dr. Bock something to live for after Barbara confronts him.
  The deaths are discovered to have been initiated by Barbara's father (Barnard Hughes), as retribution for the "inhumanity" of modern medical treatment. Drummond's victims would have been saved if they'd received prompt, appropriate treatmentâbut they didn't. Dr. Bock and Barbara use a final, accidental death of a doctor at the hospital to cover Drummond's tracks. Barbara then takes her father back to JFK airport to escape back to Mexico, leaving Dr. Bock at his insistence to try and organize the chaotic Hospital.
