A missing police gun is connected to a series of recent heists and murders. Its owner, WONG (LeeKwok Lun), vanished earlier while pursuing a suspect in the mountains. His partner, CHI-WAI (Lam Ka Tung), miraculously returned unharmed and the hot shot Regional Crime Unit Inspector, HO (Andy On), is in charge of the investigation. HO knows the only chance he has in cracking the case is to ask for help from his mentor/former boss BUN (Lau Ching Wan), a gifted criminal profiler now living in seclusion with his wife MAY (Kelly Lin). BUN puts himself in the victim's place, literally, and his unorthodox approach has put doubt in HO's mind who feels betrayed when BUN's investigation goes beyond his imagination. What begins as a quest for answers has now taken a schizophrenic turn where truth and lies, reality and delusions intertwine in this indie action comedy from IFC Films.
