You've just started a new job — as a 911 dispatcher.

Your first shift should be simple: sit down at the computer, take calls, listen carefully to people, and decide whether a police unit needs to be sent. At first, everything seems ordinary. Suspicious individuals, fights, noise complaints, domestic incidents — the usual dispatcher's work. But then a call comes in from an unknown number. A frightened girl begs for help and gives an address. Your colleague insists it's just an old system glitch. According to him, this call is connected to a case that was closed many years ago. But something about this story won't leave you alone. You decide to check the address yourself.

An ordinary night shift gradually turns into a grim investigation, where one strange call leads deeper and deeper into a story everyone thought was long over.
