"The Thaw" starring Jo Jin-woong, Kim Dae-myung, and Shin Gu started filming at the Namyangju General Studio on July 20. The film was produced by WithusFilm, the production company of "The Attorney", and distributed by Lotte. The film is a psychological thriller that tells the story of the frozen Han River slowly melting, the headless female corpse under the ice surface floating to the surface, and the secret of the serial killer gradually revealed. Jo Jin-woong plays the role of the internal medicine doctor Seung-hoon, who opened a hospital in Gangnam but went bankrupt. After that, he was hired to work in the hospital of his predecessor, but was involved in the secret of the serial murder case. After filming the first scene, Jo Jin-woong said, "It should be a very interesting thriller. Today is the first filming of "The Thaw", and I am very excited and nervous. I hope to make this movie step by step." Kim Dae-myung and Shin Gu play the father and son Seong-geun and the old man Jung, who are the owners of the single room that Seung-hoon has just moved into. They also run a butcher shop and are suspected by Seung-hoon because they are related to the secret of the serial killer. Song Young-chang plays the role of a man who always appears in front of Seung-hoon and asks questions about the serial killer, while Lee Cheong-ah plays the role of Mi-yeon, a nurse in the internal medicine department, who also always hangs around Seung-hoon. The film is directed by Lee Su-yeon, the director of "Table for Four," and is expected to be released in the first half of next year.
