## Synopsis (in-house rewrite)

Dimly lit room. Metallic tang. The scrape of heavy boots.

They awaken, one by one, to find themselves prisoners of brutal geometry. Each identical chamber leads to another, and another, and another. Death waits behind the wrong door.

A J-horror remake that understands closed-room dread.

**Mood tags**: dread, mindfuck
