The main character in the film is a teenager named Lyosha, an enthusiastic computer games player, spending all his time in special clubs. Following his passion, he almost did not pay attention to others: neither to his mother, who was distressed by the fact that her son had dropped out of studies, nor to his girlfriend Katya, who was in love with him, nor to any of his friends. In an environment of professional gamers Lyosha becomes one of the best, followed by victories in multiple competitions. In an effort to become the best he embarks on an international gaming tournament in Los Angeles, but he takes only the second place. After returning home, Lyosha gets rid of his gaming devices, and for the first time during the entire film, a smile appears on his face.^[6][7]
