年迈的地质学家安德龙·弗谢斯拉维奇踏上了一段由莫斯科到北贝加尔斯克的火车之旅。一路上，他一边翻看年轻时的照片，一边追忆起70年代末勘探贝阿铁路的时光。这条铁路穿过广袤的西伯利亚，是苏联历史上最昂贵的项目。 　　An aged geologist, Andron Vseslavich, goes on a train journey from Moscow to Severobaikalsk. On the way, he goes through photos of his youth, remembering how in the late 70s he scouted the future route of the Baikal-Amur Mainline, which runs through the vast expanses of Siberia. It became the most expensive project in Soviet history.
