In 1988, when Kimball is only four years old, her mother attempts suicide on Mother's Day—and this becomes one of many things Kimball's family never speaks about. As she searches for answers nearly thirty years later, Kimball embarks on a journey into the secrets her family has kept for decades.

Using old diary entries, hospital records, home videos, and other archives, Margaret pieces together a narrative map of her childhood—her mother's bipolar disorder, her grandmother's institutionalization, and her brother's increasing struggles—in an attempt to understand what no one likes to talk about: the fractures in her family.
