Raggedy, dirt-smeared and undersized, Danny (Dwayne “The Rock” Johnson) wears a metal collar and lurks passively on the sidelines as his boss, a burly gangster (Morgan Freeman), demands payment from a client. When the client balks, the crime boss unfastens the smaller man’s collar and barks, “Get ’em!” Danny springs into action, beating to a bloody pulp the client and at least a dozen henchmen. “He got away,” the gangster says afterward, patting an expressionless Danny the way one would a dog and reattaching his collar.
