This movie more than 25 years old(western)

Sorry, I've Googled a bit on and off but sadly I'm getting nothing for this one. Was the loss of his wife and child told via flashbacks or did the film begin in the US and then move on to Asia? I doubt that would help me much but it just might trigger something for someone else. Also what language was this in - English, a foreign language or a mix?
