Ashk-e Sarma

Set in 1983, during the Iraq-Iran war, at an isolated outpost in Iranian Kurdistan, soldiers find themselves unable to tell friend from foe as local insurgents pick them off with improvised explosives and roadside bombs. The Iranians bring in a bomb expert who decides that the key to success is earning the sympathy of the people. This he does by falling in love with a pretty shepherdess who is also a spy for the rebels.
