Betty and her friend V have a major project: the open-air music festival, Sziget Festival held every summer on one of the Danube islands in Hungary. Instead of money the teenagers have a stash of grass waiting for a buyer. Food? Nothing wrong with the leftovers from other people's plates. Tent? Why bother when you can sleep under the stars. Sleep? No way: the party goes on all night. V is a pretty girl who knows how to use her charms to the best advantage. Betty, more reserved and shy, never quite knows what to do with her hands, how to hold a cigarette, what to say to the boys they meet. But the tables are turned when the pair go their separate ways after an argument.
