From the back of the book:
Fiasco is a game inspired by films like Blood Simple, Fargo, and A Simple Plan. During a session you and your friends will engineer and play out stupid, disastrous situations that exist at the darkly comic intersection of greed, fear and lust. It's like making your own Coen brothers movie - in about the same amount of time it'd take to watch one.
For 3-5 players and 2-3 hours. No preparation required!
