Robbie Coltrane stars as Fitz, a brilliant but flawed, wise-cracking criminal psychologist who looks behind the evidence of a murder to discover what lies within the criminal mind. The local police in Hong Kong are looking into the apparently motiveless murder of a businessman. Getting nowhere and requiring a quick result, they call in Fitz to assist on the case. While working in a foreign location, in a different culture, with detectives not used to serial murder, Fitz is confronted with yet another murder. With time running out, Fitz is convinced that a western ex-patriot is behind the brutal slayings, but can he make the connection in time?
