Karen has come home to Nova Scotia for the first time in a decade to oversee her mother's funeral and tend to her affairs. Irene, a trained nurse, had spent her life caring for Karen's older sister Kelli, who was born with a developmental disability. Before her death, Irene had secured a placement for Kelli at the Seaside Care Facility, but after the funeral, in a fog of guilt and grief over her neglect of Irene and Kelli over the years, Karen starts to second-guess her mother's instructions. Not knowing which way to turn, she begins to depend on Trevor, one of Kelli's caregivers, for both advice and support, trusting him all the more once she learns how close he was to Irene. Slowly, Trevor insinuates himself into Karen and Kelli's lives.
