Years ago, a teenage girl named Lily escaped the secluded Whitlow Institute, a psychiatric retreat her parents had sent her to, and escaped from the institute into a new life as Claire Ashford. She thought she left it behind. She was wrong.
When the Montana Bureau of Investigation uncovers evidence of a restricted floor at Whitlow, Claire is brought back as the only former patient who made it out. Inside, a low, constant hum moves through the walls, the mirrors do not reflect reality, something she remembers but cannot explain.
Investigators uncover Level 4, where patients weren't treated they were studied, mapped, and quietly replicated as part of a banned research program.
