David Mann (Dennis Weaver) is trying to drive his car across California. When he tries to pass a gas tanker, the driver somehow takes offence. At first the unseen driver just annoys David by continually passing him and slowing down. Then he starts playing mind games with David, tempting him to pass the tanker, only to prevent him when he tries. The story is seen from Davids point of view, with commentary as he thinks to himself.
