South Korean filmmaker Lee Jong-hyeok makes his directorial debut with the psychological thriller H. Head cop Kim Mi-yeon (Yeom Jeong-ah) and detective Kang (Ji Jin-heui) lead an investigation of several copycat murders. It seems that all the recently gruesome murders are mimicked in the style of serial killer Shin Hyeon (Jo Seung-woo), who is locked in prison on death row. After the suspects start getting killed in the same way, Kim and Kang seek the help of psychiatrist Chu Gyeong-suk (Kim Seon-gyeong) to get some answers. H was shown at the 2003 Cannes Film Festival.
