Film's distributor Showbox announced in a press release on Wednesday that the Lee Byeong-Heon starrer will hit local theaters on August 11 and released two official movie posters featuring Lee and Choi Min-sik.

With two of the country's top actors in the lead roles, the thriller pic is being lauded as one of the year's most anticipated movies.
