A modern incarnation of a muscle car, a silver mustang in this case, rumbles across the screen. A woman in a red dress and high heels, her legs noticeably scuffed and scraped and bloodied, emerges. In casual but deliberate fashion, she walks across an auto shop. She asks a question of the mechanic working beneath a car. When he pokes his head out to answer, she smashes him with a sledgehammer. So begins South Korean director Lim Kyoung-tack’s revenge thriller No Mercy.
