DR. MAN, an unorthodox psychiatrist, is skilled at extracting the deepest secrets of his patients. One day, he hops into a random cab and encounters CHOI, the cab driver. MAN finds CHOI's condition deeply disturbing but is unable to express his concern during the short cab ride. A few days later, the two men cross paths again. CHOI has been ordered to undergo a psychiatric evaluation due to his alleged involvement in reckless driving, and MAN is assigned to his case. MAN quickly realizes that CHOI struggles to differentiate between dreams and reality. He constantly sees "devils". Awake or not, his mind can never rests; his body continues to waste away. As hopeless as CHOI’s condition seems, MAN is determined to get to the bottom of his story. As CHOI's story unfolds, MAN begins to experience disturbing and perplexing dreams. These dreams are vivid and unsettling. The deeper MAN delves into CHOI's past, the more intense and haunting his nightmares become. MAN becomes increasingly suspicious of what is causing his condition. Are his night terrors a result of repressed memories, or is there a price to pay for uncovering the ghosts hidden in CHOI's closet?
