Since her earliest memories, Jessica lived in the shadows of the family estate, bearing the cold hatred of her father and elder brother Elliot, who held her responsible for their mother's tragic delivery. The only warmth in her lonely existence was Ava, an affectionate childhood friend who treated her with gentle sisterly love. When Jessica receives an incurable cancer diagnosis, she chooses to quietly disappear rather than burden her household.
Elliot uncovers forgotten medical diaries proving their mother died from a pre-existing hereditary heart condition, wholly exonerating the sister he abused for decades. Frantically scouring the province, Elliot arrives only to find Jessica's empty hospice room and her final birthday farewell letter. Left drowning in irreversible remorse, Elliot faces a lifetime of agonizing grief for the sister he broke.
