Silent Soldiers tells the stories of soldiers on the battlefield. The film is set amongst the opening of the campaign against Buon Ma Thuot. The troops hid in the rubber forest waiting for orders. Old Lung and his daughter Ho May are the silent soldiers operating in the enemy's heart, as scouts for the army. News of Gia Lung's father and son helped the army capture Buon Ma Thuot.
The girls are young, beautiful, but no less clever and courageous to execute the judgments of the Revolutionary Court (named the "rose" plans) in order to hit the enemy's psyche and contribute increasing pressure for the US imperialists to withdraw their troops and affirm Vietnam's position at the negotiating table for the Paris Agreement.
