一辆青绿色的轿车，司机是黑人，乘客是白人

Tony Lip, a bouncer in 1962, is hired to drive pianist Don Shirley on a tour through the Deep South in the days when African Americans, forced to find alternate accommodations and services due to segregation laws below the Mason-Dixon Line, relied on a guide called The Negro Motorist Green Book.

In 1936, Victor H. Green (1892-1960) published The Negro Motorist Green Book, a book that was both a travel guide and a survival manual, to help African-Americans navigate safe those regions of the United States where segregation and Jim Crow laws were disgracefully applied.
