Wit takes place in a University Hospital Comprehensive Cancer Center. The main character, Vivian Bearing, Ph.D., is a John Donne scholar who has stage IV ovarian cancer. Much of the action takes place in the last few days/hours of her life, although flashback scenes to weeks, months, even years before are interspersed effectively throughout the performance.
Bearing has lived an isolated life. Her love is her teaching and research. She is a stern taskmaster, perhaps "non-humanistic" in her approach. Similarly, she faces doctors and a medical system that emphasize technique over caring. She does find, in the end, compassion from a nurse who prevents the medical team from carrying out a CPR (cardiopulmonary resuscitation) attempt that she did not want.
