Inside a ruined submarine shaped like a giant eye , a man named Bob crawls through shattered glass with bloodied hands. He is hunted by faceless silhouettes and reaching hands that pull him through the "Black Mirror"—a dark, watery void where reality fractures. There, he encounters the "Burning Man," a reflection of his own suffering who offers him a "mirror-apple" (Ogluka) made of sharp shards. To escape the closing walls of his mechanical prison, Bob must confront a cryptic mantra and consume the very fragments that wound him, leading to a violent, transcendent release.
