I am in search for help for a movie whose title I don't remember and which I rented many years ago as VHS.
The general plot is about members of a border patrol in a mountain landscape (may Alpine) and with the border guards having sex with eachother or with refugees/immigrants they caught crossing border illlegally and the sex scenes are both outdoors an at the border patrol base.

First I thought it may have been "War Diaries" released by All Worlds Video, but the pictures on the covers and the guys being shown on them on GEVI are looking too different to what I remember from the movie I am searching for. According to my remembrance the outdoor scenes were most at dawn or night.
My vage memory gives me a title in French which I remembered in the past as something like "Le cache de Martin" or "Le cachet de Martin" which I took for something like Martin's Diary. But past research with these French titles lead to nothing. Because of the may be French titles and the may be Alpine setting I guess it may have been a European production.

The only other thing I remember is that one of the actors was the same "Valentin" you can see on the front cover of Hollywood Sales "Valentin's Hard Interviews"/"Les Entretiens Bandes de Valentin" https://www.gayeroticvideoindex.com/V/8/18838.html

Thanks in advance.
