In the late summer of 2014, at the height of the armed conflict in the east of Ukraine, two volunteers - machine gunner KABAN [Wild Boar] and platoon commander SHEVA - are on active duty at the Ukraine-Russia border. Kaban was discharged from military service due to a concussion several years ago. Now he tries to return to his airborne assault company and go into military action as soon as possible. Sheva, an intellectual and IT professional, dreams to liberate his home city Donetsk from the separatist rebels. The area around the border outpost has been shelled by Russian artillery for a week. While local residents are fleeing their homes and the Ukrainian troops are retreating, the border guards do not leave their positions. ADVOKAT [Lawyer], driving an infantry fighting vehicle, breaks through to the border outpost from the encircled Savur-Mohyla hill and stays to help defend the border. Kaban is severely wounded in a fierce combat with separatists.
