A talented black pianist, known as a doctor, resolutely went to the south where racial discrimination is very serious to make the tour go smoothly in order to change the ideal of "because genius is not impressive". I found a white gangster and worked as a driver and assistant in nightclubs all the year round. Gangsters are nonsense, which can make the lower classes (such as grassroots police, gangsters, etc. ) willing to listen to him. In the process of traveling in the south, he encountered all kinds of difficulties and indecencies, as well as behaviors and habits that discriminated against blacks. With the help of drivers who are quite experienced in gangsters at the bottom of society (also known as the voice of the people), he saved the day, while the black pianist who is "vulgar" in the eyes of ordinary people constantly influenced and educated the gangsters' drivers, so that his ideological consciousness was qualitatively improved and he won the respect and love of his family and friends. In the process of constant performance, constant events make them help each other, care for each other, change each other and upgrade their friendship.

There are many places in the film that can touch our society and hearts: for example, in the section of assaulting a police officer, violence cannot solve the problem, and only by winning respect and maintaining self-esteem can we win (dignity always prevails). For example, in the face of misunderstanding and prejudice, (the world is full of lonely people who dare not take the initiative), it is a good film to hit the soul directly.
