Clint Eastwood stars as Earl Stone, a man in his eighties who is broke, alone, and facing foreclosure of his business when he accepts a job that simply requires him to drive. Unbeknownst to Earl, he's just signed on as a drug courier for a Mexican cartel. As his money problems become a thing of the past, Earl's crimes start to weigh heavily on him, and it's uncertain if he'll have time to right those wrongs before law enforcement, or the cartel's enforcers, catch up to him.
