In the Yom Kippur War, there are 42 soldiers, under the command of a young lieutenant, in the "HaMazakh" outpost (an isolated outpost on the banks of the Suez Canal), in order to repel Egyptian enemy attacks. During the intense fighting, half of the soldiers are killed, while at the same time in the IDF bunker a Tel Aviv reserve doctor fights for the lives of the many wounded, and calls for urgent evacuation. After a week of siege and stubborn fighting, the soldiers realize that all rescue attempts have failed, the ammunition is running out and they are preparing for a fateful battle. A sharp confrontation between the commander of the outpost who calls to fight to the last bullet - and between the doctor who pushes for an orderly surrender to the Egyptians in order to save the lives of the wounded.
