The scene I remember involves a group of middle-aged guys (maybe 5 of them, I believe they were all white but not 100% sure on this) walking through a rural plains-like area. Somehow, they get stuck around waist deep in mud, quicksand, or something like that. They sing the Internationale as the sun sets on them.
I saw it while flipping channels but couldn't stick around to watch it. The vibe struck me as indie but I can't say for sure.
