Parkour spreads all over the planet at the speed of the Internet. The "District 13" and "Yamakasi" movies revealed new opportunities for self-development of the human. Now in every courtyard you can find tracers - children who are fond of parkour. The tracer today is a child of the city. His career is a free man running out any obstacles and fears. He is equally fond of heights and the abyss. Tracer loves jumping, because it gives him a sense of flight, and he loves running, because he is ahead of time. But sometimes things go wrong... Based on a true story.
