Newly married couple, Luke and Scarlet Newton, move into an affluent suburban neighborhood where they befriend two neighboring families: the grieving but obsessive Barlows, whose son vanished years earlier, and the seemingly confident Whitlocks, whose home hides severe domestic abuse and addiction. As social gatherings draw the neighbors closer, cracks emerge—Jack Whitlock’s violent control over his wife and son, Luke’s growing moral drift, and Scarlet’s increasing frustration with Luke’s passivity and refusal to confront wrongdoing. Meanwhile, Nathan Barlow quietly continues investigating his missing son, forming uneasy emotional connections that blur boundaries and escalate tensions that entangle everyone next door.
