Sidney Winawer is a New York physician specializing in gastrointestinal cancers. When his wife, Andrea, is diagnosed with stomach cancer, he is made to see his own work from a new perspective, that of the patient and her family. The experience gives him new insights into aspects of health care he had not considered before, such as the alienating effects of some hospital routines on patient and family, the patient's need to find hope from any source, regardless of its intellectual provenance, and, encouragingly, the life-enhancing effects on his family as they join Andrea in her determined struggle to prolong and enrich whatever time remains for her.

For the first time, Winawer explores alternative and complementary approaches to cancer treatment, including meditation, antioxidant therapies, hyperthermia, and other attempts to stimulate the immune system. At first resistant, he comes to recognize the need for the terminally ill and their families to have access to as many resources as possible, and eventually it becomes his "mission" to emphasize the need for practitioners of conventional medicine to learn as much as possible about integrative medicine.

An interesting subplot is the story of Dr. Casper Schmidt, Andrea's psychiatrist, whose remarkable knowledge of new treatments for terminal illness is explained when he dies of AIDS. As another physician led by personal experience of disease to explore beyond the boundaries of conventional therapies, Schmidt forms an illuminating counterpoint to Winawer himself.
