How bad is it? One of David Prior's better war films; in other words, dreadful.
Should you see it? No.
David A. Prior has a cult following among bad movie fans and this film is one of his better, thus less interesting, directorial efforts. A courier with a classified document is lost in Vietnam during the war and a platoon search for him, only to find it's a plan to sell weapons to the enemy. Joe Spinell is the only name actor and he has little to do. There's way too many plot twisting double-crosses to follow, but that doesn't matter, as the film is just explosions (too far away from those who react) and shirts filled with squibs. The music is way too cheerful for the serious scenes, the scenery and clothes scream 1980's California rather than 1960's Vietnam, there's an unexplained Australian and at least two dead characters return later in the film.
