2000年，俄罗斯发动的第二次车臣战争进入扫尾阶段，俄军攻克车臣首府格罗兹尼。其中，有一股车臣非法武装分子被俄军包围在阿尔贡峡谷，他们企图劫持平民逃出边境。此时，俄76空降师属104近卫伞降团第2营临危受命，封锁敌军。其中，多罗宁（迈克•普莱切科夫 Mikhail Porechenkov 饰）率领的作战小分队，接到的命令是便是在在四面环山的阿尔贡峡谷阻击叛军通过。然而，由泰姆拉率领的车臣叛军竟有千人之众。面对敌人的疯狂进攻，他们进行着顽强不屈的抵抗。最后，大家壮烈牺牲。多罗宁在临死前，脑海中浮现出与女友阿利桑德罗道别时的情景。他把女友的地址交给了战友，而战友们也接连倒下了。炮声隆隆，硝烟弥漫，战争的幸存者寥寥无几……
本片根据俄罗斯报告文学《连队消逝在天际》改编，取材自俄罗斯平叛车臣的真实战役。

The true story is of Ivan Sanchin, the KGB officer who was Stalin's private film projectionist from 1939 until Stalin's death. Told from Sanchin's view, the sympathetic but tragically flawed hero, squirrel, maintains unwavering faith in his "Master" despite the arrest of his neighbors and his involvement with their daughter, his wife's affair with the chilling State Security chief Lavrentii Beria and her tragic decline, and the deadly political machinations within the Kremlin he witnesses firsthand.
