On their way back to the station, Marie and her colleague spot a car racing at high speed through the city and running red traffic lights. The two officers immediately set off in pursuit. They manage to force the driver to stop, but, without warning, the young man pulls out a gun and shoots Marie's colleague. Marie returns fire in self-defence. With the driver of the car mortally wounded, Marie falls to the ground and loses consciousness. The young archaeologist Paul, who has witnessed everything while at a celebration in a nearby café, immediately gives Marie first aid. Both have no idea that this encounter will change their lives.
