The film begins in the 1980s Soviet Union. Two best friends, Orlov and Muravyev, are serving at the Black Sea Navy Base in Sevastopol, Crimea. Both fall in love with one beautiful girl Nelly, and their friendship suffers a first blow. Because she picks Muravyev, his friend Orlov struggles with an inferiority complex and becomes a secretive alcoholic. After the collapse of the Soviet Union in 1991, both friends are transferred to the Northern Fleet on the Polar Ocean. One day their sub is performing a routine training. A disturbed WWII mine slowly moves on a collision course with the sub. A mighty blast knocks down everyone inside the wrecked sub, 72 meters below the sea level. Then ensues a nerve-racking struggle for survival. 灾难片竟发展为文艺小品。...。生存？毁灭？。安德烈海军旗~飘扬！。军队发展关系国家安全。很个人，很震撼。好在哪里？。一点零碎的观后感。 俄罗斯最新灾难片，根据俄前海军将领Alexander Pokrovsky回忆录改编，部分情节取材自2000年俄罗斯核潜艇“库尔斯克”号沉船事件。描写搁浅在海底72米深处的潜艇船员进行自我拯救的故事。该片配乐由电影音乐教父恩尼奥.莫里康内（Ennio Morricone ）担任。
