Posthumous Memories is a comedic drama that follows the journey of a wealthy man after his death. Set in 19th-century Brazil, the film explores themes of wealth, classic literature, and the social norms of the time. Through a series of narrations and flashbacks, the protagonist's posthumous adventures and encounters with horse-and-carriage rides, coffins, and societal traditions make for an entertaining and thought-provoking story.

The film follows Manuel Maria du Bocage, 18th-century poet, as he travels through the world from orgy to orgy and from excess to excess.
