Hi Guys

I would like to know if anyone knows the name of the Documentery that was shot in 1974 of the RLI

I saw it once many years ago and one of the chapters or scenes was shot with my fathers troop at mount darwin in 1974 and I think it was in Afrikaans although I can not remember as I was still a young boy when I saw it

I am desperately looking for the movie again and was hoping that someone here might know what it was called

Thank you
