Multi-award winning actor Brian Cox plays reclusive Avery Ludlow, a small-town shop owner whose only reason for living is his dog, Red. When bored and bad-seed teens savagely kill the animal, Avery becomes determined to settle the score by wreaking vengeance by whatever means possible, whether within the law, or not. But when Ludlow learns more about one of the killers, he finds himself conflicted by his desires for revenge and by the memory of a long-held secret. Based on the novel by cult thriller writer Jack Ketchum, Red is a finely detailed character study of what motivates an otherwise quiet man to become obsessed with retribution.
