In a dramatic monologue, Joanne traces the devastation of a familial proclivity to breast cancer through four generations of women: her grandmother Sarah; her mother; Joanne herself and her two daughters, one of whom is also Sarah.

Joanne’s mother and grandmother both died very young of breast cancer; however, many other family members vanished in the Holocaust and the number of familial cancer deaths is insufficient for her to qualify for genetic testing. Her friend Linda, also a mother of two daughters, learns too late that she carries the BRCA gene; she urges Joanne to be tested.

Tormented by not knowing and equally tormented by what should be done if the test is positive—both for herself and her daughters, she convinces a doctor to lie so that the test can be performed. It is positive; Joanne opts for bilateral preventative mastectomies. During a visit to the gravesite of her mother and grandmother, she begins to explain the genetic risk to her daughters.
