¿Os suena?plot evolves around two brothers ? - simple peasants without much knowledge of what's goin on - persuaded ( by their's landowners ?) to join the fight on Franco's side -
- there was some love story with some equal simple peasant women (maybe also sisters)...
- catching and executing of russians parashooted spies ( one was a woman) - or maybe it was just a shot down plane crew - at some marsh/forest location...
at the end of the movie when the republican forces were advancing to their village/town the guys who enlisted them - executed our protagonists shooting them at the back, and then just put on the red armbands and joined the enemy ranks.
it was black and white and I believe ( thought I'm not sure of it) that it was stylised as silent with title cards instead of dialogs
I saw it on german Arte via satellite late at night, somewhere in the 90's and I'd like to watch it again but so far no luck in finding the title...
Saludos.
