Four women formed an orchestra in prison. They used music to get rid of the shackles of the prison. On their way to a police dance, they tried to escape, and rock conveyed the deepest cry of their hearts. Under the close arrest of the police, the Bandis Orchestra again and again escaped the police capture and sang, and soon became famous, but the support of its supporters could not be exchanged for freedom. At a time when they were at a dead end, they gathered together again for a perfect singing. In the whole process of escape, the demonstration of friendship and the test of human nature are vivid in my mind. The whole story is full of rock and roll, and it is also a new song for the old tune of road movies.
