“Line Of Duty” (*** out of four) was an arresting melodrama about a disgraced and disgruntled cop (Aaron Eckhart) who finds himself in a race against time as he attempts to find the kidnap victim of an abductor he shot and killed earlier on in the day! Nonstop story literally doesn’t stop to take a breath and throws you right in the midst of things from the opening scenes. Story becomes a little arbitrary and silly towards the end but it never stops being tense and wired. Eckhart’s usual rock-solid performance helps you overlook some script weaknesses and holes.
