After a surprise Egyptian attack, 42 soldiers under the command of a young lieutenant from the Seder yeshiva, struggle to repel the enemy attacks during which many of the fighters are injured or killed. At the same time in the TAGD bunker, the Tel Avivian reserve doctor is fighting for the lives of the wounded fighters and calls for urgent evacuations that do not come. After a week of siege and fighting, the soldiers will have to choose whether to continue fighting under the orders of their commander, or to follow the plan of the reserve doctor - a plan that may save their lives. Will they decide to give up the values they were raised on and surrender, or will they fight to the last bullet?
