It was the last days of June 1942. The fascist troops were tearing towards Sevastopol, and fighting was already going on in the city itself. Ships of the Black Sea Fleet had already broken through to Sevastopol more than once, delivering replenishment, ammunition and weapons. And now, destroyers "Daring" and "Stremitelny" receive a new order to go to Sevastopol. This way is known to sailors well enough, but the fascists repeatedly mined the only fairway to Sevastopol, and enemy aircraft constantly attacking destroyers. At the cost of losing the "Daring" sailors manage to break through to Sevastopol. But the hardest tests fall to the sailors on the way back, when overloaded with wounded "Stremitelny" returns to his native port.
