The central character is a garage mechanic named Robert (Jean-Marc Thibault), who returns a car to its owner on a Sunday morning. Unbeknownst to both Robert and the motorist, the steering mechanism has not been properly tightened. When Robert realizes that the car is a potential death trap, he desperately tries to contact the owner, who has left for parts unknown. Before the day is over, virtually every law enforcement official within a radius of 50 miles is on the lookout for the faulty car. Tension mounts to the breaking point as the driver presses down on the accelerator, thereby figuratively condemning himself and his family to a horrible death if he isn't stopped in time. Dimanche was one of the year's biggest hits on the European film-festival circuit.
