Young Dr.
Bromgard has come to a small country town to assume a new practice.
No sooner has he arrived than he receives word that a colleague, Dr.
Polyakov, has fallen gravely ill.
Before Bromgard can go to his friend's aid, Polyakov is brought to his practice in the middle of the night with a self-inflicted gunshot wound, and, barely conscious, gives Bromgard his journal before dying.
What Bromgard uncovers in the entries is Polyakov's uncontrollable and merciless descent into morphine addiction -- his first injection to ease his back pain, the thrill of the drug as it overtakes him, the looming signs of addiction, and the feverish final entries before his death.
