The film focuses on the epic struggle that took place during the Battle of Gallipoli. The Dardanelles Strait was surrounded by British forces from the Allied Powers. The British, who landed at the Arıburnu coves, intended to advance into the interior. British attacks on many fronts were repelled with great sacrifice. Those behind the front lines also assisted those on the front lines with all their might. During this time, the Turkish navy ship Muavenet-i Milliye succeeded in sinking the British navy ship Goliath. These sacrifices would herald that victory was not far off.
