A rather unconventional thriller revolving around a kind of twisted action (anti-)hero protagonist mentally broken beyond repair, who seems inevitably drawn towards the kind of traumatic situations that gave him that severe case of PTSD in the first place. This is echoed by the girl he is hired to rescue, a victim of child prostitution and clearly doomed to become a similarly broken person. Writer-director Lynne Ramsay is clearly more concerned with the inner torment of her characters than with the overall plot and achieves her vivid portrayal of their their messed up states of mind through purely cinematic language.
