A gang of skaters who fight for justice by extravagant methods is operating in Moscow. Criminals in helmets attack bribe-takers and leave a brand of "karma" on their foreheads. Alexei Yudin, a young and fresh graduate of the police academy, is given the task of infiltrating the gang under the guise of a skateboarder. In the company of his new friend Max, he learns the board and joins the skater party. But the further the task progresses, the more difficult it is for Alexei to keep impartiality. It seems that Yudin himself is imbued with the ideas of the noble bandits and understands less and less whose side he is on.
