Wide Awake (), also known as Return, is a 2007 South Korean thriller film directed by Lee Gyu-man, starring Kim Myung-min in the lead role.
In 1980s South Korea, a young boy is traumatised after experiencing anesthesia awareness during heart surgery, and no-one believes his story afterwards. Twenty-five years later, the doctors and nurses who operated on him begin to die under mysterious circumstances. Dr. Ryu Jae-woo, a surgeon married to Hee-jin, believes that the boy he remembers from his childhood is responsible for the deaths. The leading suspects are Lee Myeong-suk, who has been stalking Dr. Ryu, and the seemingly unhinged Uk-hwan. Hypnosis specialist Oh Chi-hoon also seems to know something about these deaths.
Wide Awake was released in South Korea on 8 August 2007, and its opening weekend was ranked fourth at the box office with 238,819 admissions. The film went on to receive a total of 677,939 admissions nationwide, with a gross (as of 16 September 2007) of US$4,569,126.
