Sarah Quinlan’s husband, Jack, has been haunted for decades by the untimely death of his mother when he was just a teenager, her body found in the cellar of their family farm, the circumstances a mystery. The case rocked the town where Jack was raised, and for years Jack avoided returning home. But when his beloved aunt Julia has an accident and is hospitalised in a coma, Jack and Sarah are forced to confront the past that they have long evaded.

Sarah and Jack are welcomed by the family Jack left behind all those years ago―barely a trace of the wounds that had once devastated them all. But as facts about Julia's accident begin to surface, Sarah realises that nothing about the Quinlans is what it seems.
