The book follows a young couple, the aristocratic Sir Peter Pendragon and his lover Louise Laleham. Following the First World War, Sir Peter - a veteran pilot - comes into a large inheritance, which he promptly begins to spend recklessly. Peter and Louise fall deeply in love with one another, bonding over cocaine which lifts their spirits to ungainly heights.

Together, the pair elope across France and Italy, taking increasing amounts of cocaine and combining the drug with heroin.
