After her mother's sudden death, Karen finds herself back in her childhood home in Nova Scotia for the first time in a decade, acting as full-time caregiver to Kelli, her older sister. Overwhelmed with grief and the daily needs of Kelli, who was born with a developmental disability, Karen begins to feel consumed by the isolation of her new role. On top of that, she's weighed down with guilt over her years spent keeping Kelli and their independent-to-a-fault mother, Irene, at arm's length. And so when Trevor-- one of Kelli's support workers-- oversteps his role and offers friendly advice and a shoulder to cry on, Karen gratefully accepts his somewhat overbearing friendship. When she discovers how close Trevor was to Irene, she comes to trust him all the more. But as Trevor slowly insinuates himself into Karen and Kelli's lives, Karen starts to grasp the true aspect of his relationship with her mother-- and to experience for herself the suffocating nature of Trevor's "care.".
