An intimate portrait of the world's most outstanding rhythmic gymnast Margarita Mamun, the main representative of the prestigious Russian National Team. The film presents a groundbreaking year in her life, from the 2015 World Championships to the 2016 Olympic Games. The gymnast has the chance of a lifetime to become an Olympic champion, competing with the best friend from her club, Yana Kudryavtseva. Owing to coach Irina Viner, rhythmic gymnastics in Russia is much more than just a sport discipline. It is a hermetic world and a source of great fame for gymnasts. The story about Margarita Mamun acts as a parable of the training system created by Irina Viner. What does it mean to live constantly under the pressure of expectations? Over the Limit is a film about a struggle for dreams and the solitude of a distinguished individual.
