Troubles of Mr Mareš

People gather around a car accident, in which a horse-and-carriage and a car clashed. As always, their feeling is that the coachman is simply a victim of the situation and that everything is the fault of the car driver. Using special effects, the film chooses two representatives from the crowd - Mr Kareš, who defends the car driver and Mr Mareš, who defends the coachman. The two men get into a car and go for a ride in which they can observe the behaviour of people in traffic. At first, Mr Mareš is pointing at all the mistakes of the drivers. But then they reach the countryside and meet the coachmen who are drunk, driving on the wrong side of the road, overtaking and passing on turns, coming out of side-roads unexpectedly and the like. Mr Mareš falls asleep and he has a terrible dream. He becomes a drunk coach-man stopped by a policeman, who is actually Mr Kareš, and who blames him for all the mistakes he made. Mr Mareš is glad when the dream is over, and he admits that the coachmen are also responsible for traffic accidents.
