To properly sum up this film, its about mercenaries hired to rescue a few American soldiers held captive in a P.O.W camp whose plane was shot down over the Vietnam jungles and who also carry documents that are plans for dropping an H-bomb on Hoinai.
The film opens with a convoy (Of which our heroes are apart of) being attacked by the Vietcong in a very lengthy gun fight where everybody grabs a machine gun, run around the jungle and shoot each other, the second half starts to tell the story and the final act is another machine gun battle where of course everyone grabs a machine gun, runs around the jungle and shoot each other, however the gun battles are not random they do happen for a reason but otherwise this is pretty much what this film is.
The characters are basically introduced as is and are given a little bit of development to establish their role in the film but the acting wasn't great, I saw this film dubbed in English even though it sometimes appeared if this was an English language movie, the dubbing itself was a bit off, the acting ranged from average to terrible (The main villain was terrible) the dialog was really cheesy at times.
Given this came out in 1988 it actually looks and sounds older and despite its flaws it was watchable, I wasn't bored or annoyed for one moment, in terms of recommending it I'd say bare in mind it is an old film, it is clearly low budget and the dubbing isn't perfect, otherwise it does pass the time rather nicely and its one of those films you can't really spoil for anyone, you can know the whole plot and you'd still be able to watch it.
