"These four walls keep me safe." Moth Braunn is a security guard. He watches over the island with a close eye, spending his nights in a dull and drab room where nothing much happens. One day, however, he had experienced a string of strange dreams. All happening in a monochromatic world, stuck inside a greyscale room with nothing but a man of shadows and two potted plants. As his dream world start becoming more and more strange with each passing day, he begins investigating his daily life to figure out where these dreams may have come from.
