Thoroughly disillusioned by the Vietnam War, John, a journalist (Michael Moriarty), turns to heroin smuggling. Acting as John's go-between is the equally burnt-out Ray (Nick Nolte), who delivers the narcotics stateside to the journalist's wife, Marge (Tuesday Weld). Soon, however, Ray and Marge are on the lam, chased down by the minions of crooked narcotics agent Antheil (Anthony Zerbe). Who'll Stop the Rain? was based on Robert Stone's award-winning novel Dog Soldiers.~ Hal Erickson, All Movie Guide
