Writer Ed Miller survives a car crash in a California canyon and insists his family was with him in the vehicle, though the wreck holds no sign of them. He develops severe vertigo, and sessions with a therapist become his route toward what really happened. You play through the investigation from the viewpoints of three different characters, each with a story of their own.
The tone is unsettling and psychological, with themes of obsession, control and doubt about what is real. It echoes the look and narrative devices of classic suspense films and takes loose inspiration from Hitchcock's movie rather than retelling it. It suits single-player adventure fans who like slow-building dread.
