The title of this movie refers to ‘The Negro Motorist Green-Book’, which was a guidebook for black road travellers. It was published by Victor Hugo Green from the mid-thirties to the mid-sixties when discrimination against non-wites was the norm across much of, in particular, the southern US. Green’s book helped coloured people to find accommodations, restaurants and road houses where they would be welcome.
When married couple Simon and Robyn move back to Simon’s childhood town, they go shopping for their new house and bump into Gordo, a guy Simon used to go to school with even if Simon can only vaguely place Gordo. Soon after, a small gift arrives at their house, and Gordo later shows up in person with another gift to welcome them back to the neighbourhood.
