This cult classic offers a tongue-in-cheek look at 20-something singles clubbing and partying in L.A.; it’s organized into 15 chapters from overview and preparation to partying and the morning after. Voice-over narration, charts and graphs, and visits to a research laboratory punctuate the story of a single night when groups of friends go out, drink alcohol, take drugs, dance and talk, and look for someone to go home with. Dangers, minor and major, await those who don’t plan well or behave foolishly, and the rewards, even for those who plan well, are few. But the species’ survival may depend on these rituals.
