Friends since they were small boys, Adam and Paul —and we never learn which is which— have withered into two hapless, desperate Dublin junkies, tied together by habit and necessity. A stylized, downbeat comedy, the film follows the pair through a single day, which, like every other, is entirely devoted to the business of scrounging and robbing money for drugs. The difference today is that Adam and Paul —already near rock bottom— have finally run out of luck, credit and friends.
