The phone rings. The voice on the line is alive-yet destined to die.
When 911 operator Cassie Miller answers a routine emergency call, she hears something that chills her to the bone: a terrified woman describing her own murder-hours before it happens. Soon, more voices come through the line. Different names. Different places. All victims who haven't yet been killed.
As the calls escalate, Cassie becomes trapped in a deadly game, where the line between the living and the dead is vanishing. A shadowy figure stalks her from the darkness, watching, waiting. The deeper she digs, the clearer it becomes-these voices aren't just cries for help. They're warnings. And Cassie might be the next name whispered from beyond.
