"The Ascent" is one of the greatest movies I've ever watched, the one with which I even began to somewhat identify myself with. By the way, it is based on a groundbreaking novella "Sotnikov" by Vasily Bykov [0] which is interesting to read in it's own sense.
Leonid Maryagin is "Леонид Марягин" in Russian. Here's his Wikipedia page [1] and here are the torrent links to the "Public enemy - Bukharin" [2] [3].
