Plot summary from DVD Verdict:
Ray Hicks (Nolte) is an ex-Marine who served in Vietnam first in combat and now as a merchant seaman, which allows him to come and go between Vietnam and the US. This provides him a unique opportunity to smuggle things from Southeast Asia to home, but he’s never done anything like the request from his journalist friend John Converse (Michael Moriarty, in another laid back but outstanding performance): bring 2 kilos of pure heroin from Vietnam and deliver it to his wife at home, and collect a cool 10 grand for his efforts. What seemed an easy way to make some quick cash just as quickly spirals out of control, as John Converse’s wife Marge (Tuesday Weld) is attacked by two thugs (Richard Masur and Ray Sharkey) who want to steal the heroin for themselves and their corrupt cop boss (Anthony Zerbe). Hicks shows up in time to thwart the attack, but now they’re on the run while John returns and is kidnapped to force Hicks’s hand. A mountaintop commune will provide the backdrop for the stunning confrontation.
