I saw a movie in the 80's (maybe the early 90's) and I CANNOT remember
the title. It is about 2 guys who are on vacation in Finland and
accidently cross the border into the USSR. They are taken as prisoners
into a brutal Soviet prison and one of them escapes with the help of
one of the other prisoners. I know that this is not much to work with,
but it is all I can remember.

Hi Professorman!

I am confident that the movie you have in mind is the 1986 film Born American.
