Detective Walker is a cop with an attitude like none other. His equally tough partner, Salt, and the rest of his police team must continue to enforce the law and fight the war against the corrupt underworld of drugs. But when a narcotics deal goes bad, and his officers are eliminated one by one, Walker learns that there's a fine line between right and wrong and must serve his own brand of justice...by any means necessary.
