Changing times and personal failings have brought life to a standstill for the natives of Ashton, Maine. On the far side of the river that divides the coastal town, the prosperous summer residents come and go, seemingly complacent, without having much to do with the locals.
But when Amber Waits crosses the river to take a job as a caregiver to dementia sufferer Walter Sterling, all bets are off. She finds herself thrown into the troubled lives of Walt, his distracted wife Geneva, and their resentful and reckless daughter Karen. And although he seems unaware of his surroundings, Walt begins to exert a strange influence on Amber and her friends. Karen becomes determined to make a dream come true by taking up with Robin Dunning, a local seafarer with a shadowy past and questionable future. As Amber tries to fend off one catastrophe after another, she has to muster her courage and resourcefulness to save her friends and herself.
