Alik is a young virtuoso clarinetist. He plays in a classical orchestra, which has been founded and led by his grandfather, the famous conductor Hovhannes Talyan. But unfortunately, one day, the orchestra’s business sponsor was killed. After his death the existence of the band was under the great risk. For surviving Alik performs various humiliating and low-paid work. But Alik and his grandfather hope for that the miracle will happen and the band will be saved. And the expected miracle occurs: By a strange coincidence Alik gets a cell phone, which belongs to some “Virtuoso”, and the income-calls are from just one subscriber – “Client”. Following the instructions Alik gets large prepayment, which is enough for the band’s surviving. With the money Alik also receives a large caliber gun and the order to kill. The problem is that Alik never seen the gun in his life, and most important thing is that he is a virtuoso musician, not a virtuoso killer.
