As Joyce Novak's daughter, Marnie, completes medical school and looks ahead to a surgical internship, her wedding, and a future filled with promise, a breast cancer diagnosis throws Joyce's own future into doubt. Always the caregiver, Joyce feels uncomfortable in the patient role, especially with her husband and daughter. As she progresses through a daunting treatment regimen including a biopsy, lumpectomy, and radiation, she distracts herself by planning Marnie's wedding. When the sudden death of a young heroin addict in Marnie's care forces Marnie to come face-to-face with mortality and her professional inadequacies, she also realizes she must strike a new balance between her identity as a doctor and her role as a supportive daughter. At the same time, she struggles with the stark differences between her fiancΓ©'s family background and her own and comes to understand the importance of being with someone who shares her values and experiences. Amid this profound soul-searching, both Joyce and Marnie's futures change in ways they never would have expected.
