Madness, Murder and Malpractice.

The Hospital (1971)

Directed by Arthur Hiller

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.
