No, You're Stupid (2016)

Christina wants to take revenge on her blind sister, who wants to take a prize in a popular music television show. She comes up with an evil joke in which she gives out a stage play organized by her friends for a real shoot in the Ostankino television studio. The sister believes what they are trying to convince her of, and Christina's rally becomes more and more like a mockery.
