On the streets of Boston, Tod and Buz encounter Arnie- a heroin addict in the throes of withdrawal. Tod wants to help the man. However Buz, who has had one too many experiences with junkies in his past, vehemently disagrees - Arnie's case is hopeless, he says, and not worth their time. Tod is puzzled at his usually altruistic close friend's sudden coldness, and wonders at its real cause.
