hike in the wilds and are all killed. This film was in the Deliverance/Deer Hunter style and involved a group of ex Vietnam war doctors who meet up every year to hike through the wilds. On this trip they are stalked and progressively killed until they hide in an old sawmill. The stalker turns out to be a disfigured patient from the war they “experimented” on and seeking revenge. I loved the film when I first saw it, but I was young, it was late at night, and I forgot the name. Any help appreciated.
