Against a background of war breaking out in Europe and the Mexican fiesta Day of Death, we are taken through one day in the life of Geoffrey Firmin, a British consul living in alcoholic disrepair and obscurity in a small southern Mexican town in 1939. The consul's self-destructive behaviour, perhaps a metaphor for a menaced civilization, is a source of perplexity and sadness to his nomadic, idealistic half-brother, Hugh, and his ex-wife, Yvonne, who has returned with hopes of healing Geoffrey and their broken marriage.

Adventurous Huck Finn prefers rafting on the Mississippi River rather than being a part of civilization.
