Artyom is 15 years old. This is the age when one is not yet an adult but no longer a child. And it is during this last summer of childhood that everything falls on him: the betrayal of his father who remained abroad after his tour, the first love, the friendship forever and the breakup forever. Artyom still has a skateboard, as skateboards were called in the 80s, which Soviet teenagers were only just beginning to discover. From now on Artiom only wants one thing: to win street contests at all costs.
