en Altadefinizione. Four young heroin addicts scour the streets of Melbourne in search of some good-quality narcotics – or as they call it, 'pure shit’. In the space of 48 hours, a friend dies of an overdose, they are ripped off by criminals and arrested and assaulted by police. They bungle a break-in, get chased by hooligans and one is sent to a methadone clinic. The search for drugs veers between farce and tragedy, but it never stops.
