In the quiet seaside town of Plymouth, MA, brothers Will and Daniel and sisters Carrie and Rose have all endured troubled childhoods. They've practically raised themselves, thanks to parents who have exited their lives in one way or another. Left to fend for themselves, they've managed to scrape by and start again. Yet coping with the losses has come at a cost: Will and Daniel struggle with alcohol and their splintered relationship, Carrie narrowly maintains a grip on her addiction, and Rose is drowning under the ruthless weight of exhaustion and loneliness. Rose's world is further upended when she discovers that Carrie, the person she knows best, is pregnant with Will's child - a man whose anger toward women is palpable.

But Rose's life soon changes course when she meets Daniel. Drawn to each other and longing for a sense of kinship that's always escaped them, they form a tender bond just days after meeting. But as their relationship starts to deepen, they're swept up in a vicious squall that will change their lives forever.
