312 Riverside Drive

In a city where every street is mapped, recorded, and patrolled, one address stands out: 312 Riverside Drive. According to NYPD data, it’s the most dangerous location in New York — thousands of 911 calls, hundreds of violent crimes, and an endless churn of missing persons. There's just one problem. Every time police respond, they find the same thing — no building. No entrance. No address at all. When NYPD Detectives Eva Moreno and Ray Navarro catch a missing persons case tied to 312 Riverside Drive, it feels like chasing a ghost. Their only lead is Walter Reed, a disheveled, erratic man who has been reporting many of the phantom crimes. Walter insists the crimes are real — and that his girlfriend, Marion, is being held captive inside 312 Riverside Drive by a shadowy figure known only as The Director, who rules over an invisible army terrorizing the building’s forgotten residents. At first, Walter’s story sounds like the ramblings of a broken mind. But the deeper Eva and Ray dig, the stranger the evidence becomes: A suspect who vanishes off the side of a building. A girl who disappears — and reappears three years later, with no memory of where she’s been. A train car that vanishes mid-tunnel, last seen beneath the ground where 312 Riverside should stand. Eva and Ray follow Walter’s trail to a crumbling maintenance entrance tucked away in a derelict stretch of Manhattan. Beneath the surface, they find what no one was meant to find: a vast, secret world — a terminal city, sprawling and surreal, ruled by laws no one dares speak aloud. As Eva and Ray push deeper into this world, they realize the conspiracy is bigger than a single missing woman. It's about all the people the city quietly erased. And somewhere, in the endless tunnels, Eva feels the faint pull of something she thought she'd lost forever: her missing sister. To solve the mystery — and survive — Eva and Ray must question everything they believe about reality, memory, and power. Because once you cross into the world below, not everyone gets to come back. 312 Riverside Drive is a character-driven mystery thriller, blending grounded police procedural with speculative world-building and psychological suspense. The series explores themes of loss, identity, and hidden systems of control — unfolding a layered mystery over multiple seasons, in the spirit of Dark, The OA, and Severance. Some places aren’t just forgotten. They’re hidden for a reason.
